I DID WARN YOU. I have missed you all so much that I've resorted to making up problems. No seriously, can you advise me how to remove a programme that will not remove from add or remove programmes. My son loaded a design programme called 20-20, which is 327.00mb and does not work and given problems. When I try to remove it ,it says "The log file xxxxxx is not valid or the data has been corrupted, uninstallation will not continue." Any idea how to override this warning or alternative methods, thank you guys.

Remove Programs
--------------------------------------------------
Uninstall Programs Manually

Just because Windows XP has the Add/Remove Programs feature it doesn't mean your application will appear in the list. Furthermore, even if it does appear, it's no guarantee that the uninstall feature will work. When you run across one of these situations the items listed below will help in getting rid of the application. Be aware that these steps may not remove everything associated with the application and can impact other applications on the computer. Have a backup or restore point and use caution.

*

Find the directory for the application and delete all the files in the directory. Delete the directory. e.g. click C: under My Computer then Program Files etc.
*

Open regedit (start/run regedit) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE and find the folder for the application. Delete the folder.
*

Open regedit and navigate to HKEY_CURRENT_USER\SOFTWARE and find the folder for the application. Delete the folder.
*

To remove the application entry from Add/Remove Programs (if present) open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Uninstall and find the folder for the application. Delete the folder.
*

Some applications have Services attached to them. If this is the case, navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es, locate and delete the service.
*

In Windows Explorer, navigate to the individual user settings and delete program references. Common places to check would be:

C:\Documents and Settings\All Users\Start Menu\Programs and delete relevant entries.
C:\Documents and Settings\All Users\Start Menu\Programs\Startup and delete relevant entries.
C:\Documents and Settings\%YourUserID%\Start Menu\Programs and delete relevant entries.
[Do this for each User ID listed]
C:\Documents and Settings\%YourUserID%\Start Menu\Programs\Startup and delete relevant entries.
[Do this for each User ID listed]

If no entries were found in the previous step and the application launches automatically, navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
and delete the entry.

New problem - new thread, so I split the above two posts out.

It looks like jephree got everything, except the 327Mb of disk space. Once the above is done, navigate through Windows Explorer to the installation folder and delete folder. If you are unsure you have the right folder, or if deleting it might break something else, a trick I use often is simply rename to the folder to foldername-3-28-09-delete (with "foldername" being the original name). Then leave it for a couple weeks. If no problems, I can safely go back and delete. If it causes problems, I don't have to remember the original name, I just edit out the added stuff.

With strong caution, if the above still does not work, you might want to check out the Windows Installer CleanUp Utility. I say with strong caution because with this semi-official, but unsupported Microsoft tool, you can uninstall way more than you want, and break Windows or another major application.

Gentlemen. Thank you, think I've got rid of it. Everything great but still freezing on AOL and internet searches. Think its a bad phone line, far from exchange, and a long extension from main phone box to computer(over 10 metres). Your all the biz, nice one.
