I am upgrading from ArcGIS 10.2 to ArcGIS 10.3 and I got the following error during the installation process:
Error 1310: The installer has insufficient privileges to access this directory: <Directory>. The installation cannot continue. Log on as administrator or contact your system administrator.
I logged in as an administrator and every time I got this error message I clicked retry during the installation process. Doing that I was able to upgrade to 10.3. However when I try to open arcmap, I get the error message: ArcGIS Desktop has encounter a serious application error and is unable to continue.
Any thoughts? ideas?
