Create 30 Day trial versionHi,
Does anyone have any advice on how to best develop a 30 day trial version. Assume that a timestamp when the app was first installed should be stored somewhere on the target system, but I need to understand how this can not be simply bypassed by removing this file..

Niclas,
As for ever on this kind of questions. This is not a newsgroup question. These dotnet newsgroups are easily to search on Google. Therefore if it is answered it is not hidden anymore.

Trust me, a search for "develop 30 day evaluation" on Google does not produce a very constructive response. Still think a "best practice" question is valid in this newsgroup.

Many thanks for the info. I am currently reviewing the aspose free solution which I think will meet my requirements. Cheers Niclas Show quoteHide quote "Herfried K.
