You can move most of the code from FetchUninstallInformation()
to a seperate function and use the rootkey as Parameter.

get_uninstallinfo_from_reg(HKEY_LOCAL_MACHINE);
get_uninstallinfo_from_reg(HKEY_CURRENT_USER);


I ended up creating a new patch that does something similar, while
keeping the FetchUninstallInformation function

Did you already checked, what windows does with
duplicate Programm names?

No, but I will do that in just a minute.

More hints:

    lstrcpyW(key_app, PathUninstallW);
    lstrcatW(key_app, BackSlashW);
    p = key_app+lstrlenW(PathUninstallW)+1;

Why not add the slash direct to PathUninstallW?

This was already part of the code that I copied.  Why the original
author of this code did this, I have no clue and was wondering about
that as well.

    sizeOfSubKeyName = 255;

Fixed numbers are not a good Idea (error-prone).
This value is related to "WCHAR subKeyName[256];",
but RegEnumKeyEx expect the max. size in TCHAR, including the
terminating zero, so the correct value for sizeOfSubKeyName
is 256.

A nice, automatic way is:

 sizeOfSubKeyName = sizeof(subKeyName)/sizeof(subKeyName[0]);

Such a construct works independant from the type (WCHAR / CHAR)
and the length of the String.

See above

All together looks like more than one Patch.

Like I said, I ended up rewriting the patch, and in so doing, created
a fairly large patch, because most of the functions had to be
rewritten to support an array being passed as a parameter.  The 2nd
patch actually will have to be changed a little more as well because I
didn't document anything, however I submitted it here for suggestions
so I could have a rough base to work with.
