Hi, I’ve been meaning to update my 2022 Version to the 2026 Version to use the Geo-location feature. I chose ‘Run as Administrator’ when installing the file. I also rebooted my device and made sure my graphics card was up to date. After installing, I logged in to my Trimble Account, then I get stuc…

While it is rare with a fresh install, sometimes you will need to delete a login file - login_session.dat You need to sign out and close SketchUp first. Delete the file from this location. C:\Users\USERNAME\AppData\Roaming\SketchUp\SketchUp VERSION

Hi, I did all the steps you listed. However, it still shows the same window. I also did what KyleB replied. It hasn’t changed.

Hi all, sorry I wasn’t able to update on the matter. I did submit a ticket, and they suggested deleting the ‘login_session.dat’ file in the AppData > Roaming > SketchUp 2026 folder. I have done this, and yet it still hasn’t worked for me. It still showed the same blank window as attached to my probl…

I’ve had about 4 people today with this exact problem - they’ve all been using Malwarebytes - this installs an ad blocker / cookie blocker which stops the page from loading. Disabling this immediately solves it.
