The world has turned upside down! ;)
Just upgraded a client from version 4.5 to 5.2 Advanced and the ODBC Driver is installing with the SERVER's drive letter. This causes all sorts of crazy errors in only certain parts of the program (IE crystal reports run ok, but Explorer does not). If we go into ODBC and update it to UNC, all is well, but every time they reload Sage, the ODBC defaults right back to the drive letter. Verified the sota.ini file is referencing the UNC, and no UAC or anti-virus interfering. Running in MAS90 Mode works just fine, running from server works fine. Happens running both as an application and as a service (with admin logon)
