Just installed about 6 stations with Win7-64.  Most of the time it works....occasionally get the data dictionary error.  Don't have a concrete answer, but have tried the following and in usually eventually works.  First try opening Classic using TP5wdba.exe (not sure if ti helps, but it verifies access to the server directory and that DBA can run).  After that, run Evoerpsetup.exe to make sure all the directory pointers are correct.  Then try running EVOerp.exe (maybe more than once), until the workstation install box comes up (be patient after you run evoerp.exe - on one station got the error and then about 10 seconds later, the workstation install screen came up)

Thanks for you help.
I followed your instructions.
 
It does not work with the shortcut that points to: C:\ISTS\evoerp.exe C:\ISTS
 
But if run F:\DBAMFG\evoerp.exe, it does work
 
 
 
thanks!!!
