Mar 30, 2014

As in image,i put a shortcut in startup folder for current user,that also appear in msconfig-> startup with status enabled but application is never run,If I go to that folder and dbl click on shortcut,it works,but on system startup ..nothing
i am wanting to install some application that i had on my windoes XP 32 bit....but when i try to install them to windows 8 64 bit,there pops out a message saying that the applications are not supported by the system .....Is there any way to make a 32 bit application to run on a 64 bit windows 8?
I just recently changed my OS to Win 8.1 (from Win 7) and a java application I have (*.jar) is pointing to Python to open it. This is obviously wrong. If I download the latest version of Java and install it, the icon changes and the app works great. The "jar" externsion is associated with java. When the PC is rebooted a few days later, the icon is now the Python one and "jar" is now associated with Python.
How can I get it to "stick" that *.jar is associated with Java?
Possible to open multiple instances of the desktop app or if there are any third party applications which could add such functionality. I would like to use the built in side by side app feature but for programs running in the desktop so I can have something like notepad++ or visual studio open on the left side of the screen and have a steam or twitch chat open on the right so I can free up my second monitor for full screen viewing of videos/games/websites. I know I can do this by resizing the windows manually but it is very clunky and harder to manage when I want to close a program or open new applications.
I have purchased notebook with OEM version of Windows 8 64bit. The system is not professional version of Windows 8. I would like to run 32 bit application which is not possible to install it on 64bit system.
On my old Win 7 and Win Vista and Win XP laptops I've had no problems opening and viewing my old MPEG-2 video files. My new laptop running Win 8.1 will not allow me to view them.
Windows Media Player will only recognize them as audio files - not video - though the sound will play. Real Player is the same - the application will open and begin playing a file but only as audio file. I've tried the built in Toshiba media player and it shows errors and won't open the files at all.
Again - these are conforming MPEG-2 NTSC 760X480 video file (old analog home movies) captured using an ATI video card dongle to connect to my video source and an old version of capture application ULead Video Studio. These files conform in every way to MPEG-2 standard/format and will run on all of our PC EXCEPT the new one running Win 8.
I bought and loaded a video editing application from Corel and it will open and play these files perfectly so why won't Win Media Player and Real Player recognize them when running behind Windows 8?
I am making applications with Live code in Windows 8 and when saving them as exe's they were launching then due to some bad code I had to end the explorer process and reboot my PC and now when I try to run these programs I get the error The application was unable to start correctly (0xc0000142). Click OK to close the application.I tried using sfc /scannow and it found errors but could not repair them.
I have uploaded the log file. With system restore as a last resort.
I'v been trying to get my new USB sound card (Roland Duo Capture EX) working with Pro-Tools 10, but when I choose the Roland as the playback engine on starting up ProTools, I get an error stating that it is in use by aother application.
Also, when I change the sample rate in the "Sound" window for that sound card, I get the following: "The Device is being used by another application"...
Is there some way in Windows 8 to check what applications are hogging the card?
Recently I installed latest Windows 8.1 update (Update 1/Spring update), and later latest Beta Nvidia driver. After that, an strange problem showed up. I recorded a video which represents it (look at the thumbnail 'hiding' under the previewed application ).
I'm using UxStyle and this theme: Windows 8.1 White Titlebar Dark theme by x0lis on deviantART . I tried:
Uninstalling UxStyle and themeInstalling 'normal' Nvidia driverDoing sfc /scannow but it didn't find anything particular (something about prncacla.inf, but I don't think that this causes this problem)Scanning system with antivirus (KIS 2014)Turning off and on option 'Enable preview' in Advanced setting -> PerformanceChanging theme to otherSearching about this in Google and this forum, but I didn't find anything similar but nothing worked.
Well I didn't tried uninstalling Update 1, but I would like to avoid that.
I doubleclicked on an MP4 to play it (from Explorer) and this XBox Video thing came up and played it. Fine, looks like a nice player. But when I stopped it wanted to exit the application -- can't find a way.
Oh, I can switch to ANOTHER application, but how the heck do I close this thing down? I could bring up Task Manager and kill it there (I suppose -- haven't even seen if there is still Task Manager, although I assume they would not have gotten rid of that) but there MUST be a simple way to close out an app, right?
(If not I'm going to remove that app and make sure I never accidentally bring it up again).
While shutting downing my PC, a dialogue box with title "Windows application error" is displayed and gets automatically terminated. Error code number varies each time. This problem is started after i upgraded to 8.1. How can it be retrieved ?
I have two operatings systems. Windows 7 on one drive and Windows 8 on the other. I have a program called PowerDirector 11 installed on the Windows 7 drive. I went to install the said program on the Windows 8 drive, (to be able to access it from either drive) and when I try to open or run the .exe, I get the error "The application has failed to start because the side-by-side configuration is incorrect.
I have been having sound problems with the speakers on an HP Ultrabook. There are times when the laptop speakers stop working. When this occurs, I go to Control Panel>Sound, select the speakers(only one set to select), select Configure and Test. After selecting Test, I receive the message Device In Use. The device is being used by another application. Please close any devices that are playing audio to this device and then try again. I've gone to Properties for the speakers, Advanced tab and unchecked option "Allow applications to take exclusive control of this device". I've also used Run sndvol to try to determine the application, but it only shows Device:Speakers/HP and Applications:System Sounds.
The only way I've been able to get the speakers to work is to reboot or disable and enable the driver for the IDT High Definition Audio CODEC.
If you're willing to look at the text above, you'll find that this "PATH" is totally different with the one we set in Environment Variables dialog or get from the CMD.
I want to use some executable files in "d:commonin" with my web application hosted by IIS8, but I found that the web application could not find the executable files in "d:commonin", which should exist in "PATH"
Well, though I can just put the executable files into system32,
I want to start two applications at windows start-up, but the application need administrator's privilage could not start at start-up directory or registry. I've heard these applications can start at windows start-up with Task Scheduler.
Basically, I want to have a VBScript (Or Similar) which types in a command prompt, but without interrupting what I am doing at the time. I have the code for it, just it interrupts me every time it types.
I am running windows 8 professional on my home PC and running windows 8 home on my Venue 8 Pro. I downloaded the remote desktop app on my Venue and setup a connection to my home PC. It was very easy and worked (at least on my home network) Now the first time I tried to access the computer outside my home it says that it can't find the PC. Is the connection only good with me being on the home network? Do I have to install some third party VPN to access it?
