Sanchaya Post Updation to 7.0-Error and the solution

In one of my office while upgrading to sanchaya post 7.0 an error occurs. The screen shot is given below. The error shows that
"The Device Activation Error.The physical file name NREGAEMO_data.mdf may be incorrect. Created database failed.Some file names listed cannot be created.Check Previous errors"
On consulting the error with SDC Chennai, They give the solution. 

Actually, the problem is due to the reason that you are having the POST database in the drive itself.

Logout of Sanchay Post in all systems. Goto SQL Enterprise Manager and Detach the POST database and then move the files to a folder (POST folder) created in the drive, preferably a drive in which you are not having your OS. Then, goto SQL Enterprise Manager and attach the POST database with owner SA. Then, run upgradation patch (after day end). You won't be facing the problem you have mentioned.
