Hello, sorry to dig up an old thread.
For my end user, adding an underscore to the program version re-generated a profile and the program was able to launch. Profiles and templates will need to be re-imported.
(ORIGINAL PATH)
C:\Users\<user>\AppData\Roaming\Trimble\Trimble Business Center\<Ver. number>
(CHANGE TO)
C:\Users\<user>\AppData\Roaming\Trimble\Trimble Business Center\_<Ver. number>
Thanks for starting the thread.

Subject: SAVE LAYOUT TOOL ERROR
Hoping someone can help with this error as my only option now is to wipe the hard drive and reinstall windows.
Ive tried re-installing TBC
Tried running the clean up tool and re-install
Tried running the cleanup tool and downgrading to 2024.12
Still the error persists

TBC will load but the ribbon is only half there with some tabs that I have never seen before
INSPECTION JAPAN
3D MEASURE JAPAN
CRACK DETECTION

Cannot open any existing or new projects. Options are greyed out

Any help greatly appreciated
