OS: Windows 7 Ultimate SP1 x64.
At some point I figured I can no longer update my IDE for Powershell - PowerGUI Script Editor (latest is v3.7.0.92 at the moment of writing). I am getting this error when inside the script editor -> check for updates, as well as in a standalone installation, in both cases the installation is rolled back.
In my Programs and Features I have the following relevant entries:
When I attempt to uninstall (A), I am getting this error:
Although the current version inside the script editor is shown as 3.6.0.21.
And when trying to uninstall (B), I get a standard Modify/Repair/Remove dialog, but when I do Remove, it ends up with the first error again (#1722 above). Doing Repair works, but does not solve the problem, i.e. still unable to Update.
Is there any way I can make it work again?
P.S. One may point out this to be part of superuser, yet I think it's an inherent part of Powershell development and so deserves a place on SO.
It seems the uninstall function either doesn't complete correctly or misses some important registry settings. I had the same problem, and this resolved it for me:
