I have seen that other users have had this problem in the past but none of the solutions have worked for me. I recently updated my Windows 10 laptop with a new Windows 11 laptop. I installed SU with no issues and was in the process of installing my extensions, again, with no issue. This morning I tried to install another but after logging back into my Trimble account the Extension Manager window is blank.
I logged out: no change
Logged back in: no change
Followed several suggestions from previous posts (checked that no Windows updates happened, checked file locations, changed the default internet test website): no change
I then did a full reinstall of SU Pro 2020: no change – and worse because now I have lost those extensions that were installed and working properly!
Some previous posts indicated that OneDrive was the culprit but I have disabled and fully removed OneDrive from Windows 11.
I also noticed just now as I took a screenshot that the Extension menu heading is also missing as well.
UPDATE: I did figure out how to install an extension manually and have gotten a couple installed that way. And–of course–the Extensions menu title magically appeared.
Each time SU opens it prompts me to update 3 extensions but I am unable to do that because the Extension Manager window is still blank.
Another possibility, when you installed SketchUp, did you right-click on the downloaded file and choose “run as administrator”? If no, right-click on the downloaded file and choose the repair option.
Possibly. I do know that SU worked correctly, even the Extension Manager, over the past week. The 3D and Extension Warehouses have not been available in SU 2020 for quite some time.
None of these have resolved the blank Extension Manager window . . . but I have managed to manually install most of the extensions that I use regularly. As mentioned Extension Manager functioned properly prior to yesterday morning but it had been a few days since I used it so it is hard to say when and why it actually stopped working. I find it interesting that previous posts mentioned OneDrive because I have had quite a battle reclaiming my files from OneDrive and eliminating it from my present system (it will probably rear its ugly head in a Windows update someday!) and this install of SU Pro 2020 was done after that.
While I am back up and running (I use SU in my finish carpentry/cabinetry business) I still would like to resolve this issue.
