Dear Ranjit,

The apended path as well as the path in error msg are same.  And I have checked my database file is also located at the same place.

I think it is an issue related to 32-bit and 64-bit.  My developement system is a 32-bit machine where as the run time system is a 64-bit machine

And as your database is stored in the Program Files folder, you are runing your program with admin rights ?

Remember that on Windows 7, most programs are NOT allowed to change files stored in the Program Files folder.

Microsoft recomend that you store program data files in the ProgramData folder on Windows 7.

LabVIEW has inbuild functions to get the path for the ProgramData folder, both on Windows 7 and XP.

You can make your installer place your database in the ProgramData folder automatic when intalling your program.

Dear Ranjit,

Frist of all thanks for sharing the links and other information.

Regarding the VI you can consider the same vi which you sent me for UDL EXAMPLE I have tried that also;even it doesnt work on win 7. (my vi will need hardware so its difficult to test it)

ProgramData folder can work, because I can read the database but cannot write.

when you marked solution then you were oon same PC? I am using udl file to write data to DB from last 3yrs. There must be some problem with VI only.. Although its same please share it.

I can do with ProgramData folder buy what is the problem during creation of installer file. You need to provide different path for that.
