Hi Friedrich,

I have attached a zip of a project file which is intended to insert the registry entries:
Test reg sbp.zip

and a reg file containing the entries required, but with a specific application path:
RegEntries.zip
If I import these registry entries directly using regedit they have the desired effect.

This is an export of the only registry entries that do get added by the install:
AsusBook new entries.zip

The overall effect that I am after is that my application is added to the open-with sub-menu on a right-click on a .csv or .txt file.

Thank you for your attention to this.

Best regards

Julia
