I had an install delay problem, and very slow program installation response, and so cancelled the first attempt to install TODOIST. I then downloaded a new .exe and tried again to install the program. This installer says that several .dlls were already installed, could not be modified, and I could either abort the install or ignore them. As they would be the same I chose ignore - but the installation won't run. I then used the windows 7 x 64 OS to uninstall Todoist - and I chose to uninstall everything. It completed the action, but a second attempt to install the program produced the same result. I now have done several installs and uninstalls - none of which work - and no instance of Todoist will run. I can't delete the x86 Program Files or the common files as there are said to be open somewhere else. How can I clean up the botched installation so that I can actually install a working version of this software. (Lenovo D20 workstation, 8G RAM Windows x 64 Pro) Thanks

Please remove any instances in Add/Remove Programs. Then reboot your system. Double check the Add/Remove Programs. If your willing, run a program like CCleaner to make sure all is removed.

Then download and run the installer again. Also try right clicking the installer and running as admin (even if admin).

Brendon, following your suggestions and after much to-and-fro-ing I was finally able to manually delete the Todoist folder in C:\users\Program Files (x86) and all it's errant files.

The "hung up" files were:

Todist - c:\Program Files (x86)
Todoist - c:\users\DGeorge\AppData\Local
Todoist - c:\Program Files (x86)Todoist
Todoist.Model.Xilium.dll - c:\Program Files (x86)\Todoist
Todoist.Windows.Xilium.dll - c:\Program Files (x86)\Todoist
Todoist.Model.dll - c:\Program Files (x86)\Todoist
Todoist.WinForms.Xilium.dll - c:\Program Files (x86)\Todoist

These were the items I couldn't remove - all gave an error saying, "The action can't be completed because the file is open in Todoist for Windows. Close the file and try again."

But once I delete these and the folder, the new download and installation went fine.

Thanks much.
