Ran rFactor2 update to install build 770 but the update stopped. "Removing directory: M:\rFactor2\installed\UIData\rFactor2 UI was NOT successful" "Update procedure has detected an error and stopped" Manually removed directory and Sync Manager completed the update and verification completed successfully. Now to see how I get on with the 64bit version BTW Thanks for producing a 64bit version. I haven't encountered any OOM problems yet nor have I monitored VAS usage but the 64bit version is a welcome build considering the VAS problems with MS FSX being on 32bit.
I had the same error but deleting the folder just brought another error when starting, something like "rFactor2 UI v1.0e error" After lots of research I found I had an rFactor2 UI.rfcmp installed at the Mod Manager. I had to uninstall it and delete it phisically to make rFactor2 to work.
