Hi.

 

I need to write to the HKEY_CLASSES_ROOT part in the windows registry from our PB 2017 application.

When I use RegistrySet("HKEY_CLASSES_ROOT\mykey","MyValue",RegString!,"MyValue"), it returns -1.

If I change to HKEY_CURRENT_USER, it works fine.

So I guess it has to do with permissions, and I can edit the HKEY_CLASSES_ROOT part when I run regedit.exe.

I this a known limitation in PB 2017? And is there a workaround, besides running the application as administrator?

And is perhaps the solution to use RegValueSetEx from "advapi32.dll" declared in Local External Functions?

It would be great if anyone has a working example of this. I cannot seem to find the values for the registry parts (RegValueSetEx expects a long value for HKEY_CLASSES_ROOT) or the correct parameters to write to registry using external functions.

 

It is not an option to run our application as administrator, even if it will write to the HKEY_CLASSES_ROOT just fine.

 

Br,
