I am running InnoScriptGenerator 1.0.3.1 to create an install script.
Everything works EXCEPT the registry creation. I want to create two entries…

HKEY_LOCAL_MACHINE\SOFTWARE\DocAssist
HKEY_LOCAL_MACHINE\SOFTWARE\DocAssist\InstallDir   - which has my install directory

My script lines are as follows:

[Registry]

Root: HKLM; Subkey: SOFTWARE\DocAssist; ValueType: none; Permissions: admins-full; Flags: uninsdeletekey createvalueifdoesntexist;
Root: HKLM; Subkey: SOFTWARE\DocAssist; ValueType: string; ValueName: InstallDir; ValueData: {app}; Permissions: admins-full; Flags: uninsdeletekey createvalueifdoesntexist

The script runs, does not give an error, but also does not create the entry in the registry.

When I run it from InnoScript Generator, the debug log shows

Screen Install Log

I am running this as an admin user. It is being run on Windows 7 64 bit.
The only other interesting piece of info is that in my application, when it accesses the registry, (via Delphi) I had to define the Registry as…

MyRegistry := TRegistry.Create(KEY_READ OR KEY_WOW64_64KEY);

because

MyRegistry := TRegistry.Create();

just did not work…

    Inno (unless you’ve told it otherwise) will be writing that value into the 32bit view of the registry.
    You’ve then told your app (using the KEY_WOW64_64KEY flag) to read formt he 64bit view.

    As it sounds like your app is actually a 32-bit app, just use HKLM exclusivly, and forget any 64 bit flags.
    This will cause the value to be correctly written into HKEY_LOCAL_MACHINE\SOFTWARE\DocAssist in the 32bit view (which is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\DocAssist in the 64bit view.)

    See the various articles on the Microsoft websites for more information.
