I tried to install Basecamp on my computer running Win10 and got this error message. Attached is the error log. I'm planning a road trip to Virginia and North Carolina and want to upload the route to my Garmin.
I'm also getting the same error message when installing 4.7.0 (on Win 10). I had it also on the version previous. I was able to install 4.6.2 which is the version I'm running now. I was not able to open the attached file in the original post. The log file lines which seem relevant are below.
Are you running 32-bit or 64-bit Windows 10? I'm running 32-bit and had no problems upgrading to BaseCamp 4.7. Now getting it to work correctly is another matter...
