Question about Operating Systems

Unrecognized file type

We have a custom program that runs on xp. One of the quirks is renaming a file specific to the program. This file has always been an unrecognized file type (which is ok). I accidently changed the file extension to .txt and specified excel as the program to open it with. I need to change the file extension back to what it was and not have excel open it. No matter what I do I cannot disassociate excel from this file no matter what extension I give this file. Any clues as how to "go back in time"? BTW this file is on a network and when accessing it from another computer, everything shows the way it should be, it's only when it's opened on my computer does it show the problem. Any help is appreciated.

I am tryign to uninstall fix it, get error 5006

Installation or uninstallation of an application or game fails and gives the following error code:

This issue is due to a previous installation not finishing properly

Solution 1. Rename the Installshield folder

Make sure you've enabled Show hidden files and folders.

Find and rename the Installshield folder:

Windows 32-bit: C:\Program Files\Common Files\Installshield

Windows 64-bit: C:\Program Files (x86)\Common Files\Installshield

If there is an Installshield file in the Common Files folder, rename that one also (e.g. to Installshield_OLD).

Solution 2. Remove all traces of previous uninstall

If renaming the Installshield folder had no effect, find and delete any traces of uninstalled applications.

Applications that can assist you are: Revo Uninstaller, Windows Installer Cleanup Utility , CCleaner.

Alternatively, do a manual clean-up:

Close all running programs. Then clear the Temp folder (found via input of %temp% in Start > Search or Start > Run).

Use the Windows registry editor to delete registry entries related to the program.

Restart the computer.

hope this helps

A blankscreen always a blank screen....when i turn my notebook on, it wont show anything...just a blank screen

Hi there,

Blank screen with a Blinking Cursor or just the Blank screen?
Which is your Operating system?
What Program Did You Install That You Weren't Supposed To?

That information might help us.
One note: I recently ran into something similar to your issue regarding the "Windows Logon".. There are a number of malware programs which will rename the critical "winlogon.exe" file to something else like "winlogon2.exe".. The malware then replaces the renamed file with a trojan also named "winlogon.exe". So the "bad" winlogon.exe is working as a trojan while still allowing the "good/real" winlogon.exe to sit beside it.. (The "good/real" file has an icon which looks like a blue window with a yellow half-moon inside so it's easy to identify.)

In my case, I used the XP Recovery Console to scan through the files in C:\Windows\System32 and find both the bad and the good versions of the file.. I deleted the bad file from the Recovery Console and renamed the good file back to its original/correct "winlogon.exe".. Rebooting the computer allowed it to load Windows so I could run antispyware scans and finish cleaning up the computer.

It might be worth checking..

Post back if it is not working we will be happy to help you.
Hope this helps.

Cannot find to name files in windows like greennail?

You can name the files by their format like .jpg, .txt, .rtf and etc, but this will do that if you rename it to another format that the file is, the file then will not open. You can rename these files if you go to Start- Control Panel- Folder Options. Here you choose the tab Show, select to "show the surnames to most common files" and press apply. Now you can rename the files in the format you want.

If you want TO FIND A FILE : you go to Start- Search- here you type the name of the file you want to search- then you can select to increase the search to find a specific format- and then you can choose where to find it (which drive or folder) and then press Search. Note you can also increase the search with add the date and the file size.

For saving a file with a file name, in every program you have to go to the feature FILE and then select SAVE AS. Here you type the name you want the file should be named as, and then select the folder it should be saved in.

Hope that helps
IF NOT then try to return here
Have a nice time over there

Run-time error '-2147467259 (80004005)': Unrecognized database format 'C:Windowssystem32wints.dat'.

To fix this program, you need to rename a folder containing a previous version of the installer. Open My Computer and navigate to C:Program FilesCommon Files. Right-click the Installshield folder and select Rename. You can rename the folder anything, but, as Google suggests, something like Installshield-old will give you a hint about the folder’s previous name. Close My Computer and try running the installer again. If that doesn't work tell me and I will see what I can do.

Icon change

It sounds as if you might be altering the file type extension.

A file name is made up of 2 parts - The actual name (the bit before the . ) and the file type extension (the 3 or 4 letters after the . )

By default, the file type extensions are normally hidden (as this prevents problems), but it is possible to get XP to show them by the following method:

Open 'My Documents' folder. Click Tools>Folder Options>View. Scroll down the lsit and uncheck 'hide extensions for known file types' Click Ok.

If you have got the file extensions showing and you were to change or delete one the icon will change. The file type extension basically tells the computer what type of file it is, and which program should open it (and shows the appropriate programs icon.)

Ensure your files have the correct extension and the reverse the above steps to 'hide' them.

Hope this helps.

When you rename a word file you need to keep the .doc file extension for it to open again in word. .xls for excel etc.

You may not have the file options visible in windows explorer. Go to tools > folder options > view and untick "hide file extensions for known file types.

If you mess it up you can open via windows explorer. Right click the file and choose openwith and select the appropriate program.
