When I try to install a new version, it tells me the old version cannot be removed
You have two options:
-
Download the installer for the version you've already installed. You can find the link to the archive of older TSVN version on our download-page. Doubleclick on the msi file and choose repair. After that, you can install the newer version without problems.
-
Try here: http://windowsxp.mvps.org/MSICLEAN.htm
This tool will clean up a corrupted installation. Then after that, you must delete the folder where TSVN was installed (usually c:\program files\TortoiseSVN). If you can't remove it because some files are still in use, get ClearInstall.exe from our website and run it. It will remove all registry keys TSVN needs to register itself in the shell. After a reboot you will then be able to delete the TSVN folder.
