I want to uninstall tortoisehg 3.1.1 from a Windows 7 machine (64 bit), but the setup program fails with the error "unable to write to Config.Msi", similar to one of the error messages from this question: Impossible to uninstall outlook addin multiuser x64
Here is what I've tried:
- Changing the permissions of Config.Msi so everyone has full control. Made no difference.
- Uninstalling from control panel add/remove programs. It just results in the same error.
- Reinstalling TortoiseHg again, on top of existing install. However, the setup program is "helpful" and detects that an install already exists. So it only gives the options to change/repair/remove the existing install.
- Run setup with change/repair/remove options. All three fail with same error
So I am stuck. my ultimate goal is just to do a clean reinstall of the tool. I have looked for the procedure to perform a manual uninstall and haven't found one. Does anyone know how to do this?
