Error while using excel

Dear All,

We have a custom program in which we are using OLE related coding.

The program is working fine with most of the users however only with few users it is throwing error while creating excel application

CREATE OBJECT application 'Excel.Application'. this is throwing error not able to upload excel data.

Any Idea what might have caused this issue to appear only for few users?

On same machine, if other user uses this tcode, it works fine. If this user uses another machine he gets same error which he was getting in his system.

What need to be checked specific to user? Please let us know.

Thanks in advance,

Jay
