Inno Installer, How to Register OCX files on Vista and Win 7

I am using InnoInstaller to create an install package for my app. On Windows XP everything works like a charm,, but when a user is installing the application on Vista or Win 7 the installer fails to install and register ocx files (I am primarily referring to 64 bit Vista and Win 7)

Specifically the issue is with RichTX32.ocx, ComDlg32.ocx and mswinsck.ocx

Can someone point out what is wrong with my installer script or help me resolve this. I found that when users MANUALLY go to register files they actually have to disable UAC on their machine,, register the files and then enable UAC back.

Code:

#define MyAppName "MyApp"
#define MyAppVerName "MyApp 1.0.0"
#define MyAppPublisher "Me The Publisher"
#define MyAppURL "http://www.MyApp.com/"
#define MyAppExeName "MyApp.exe"

Hmmm.... Try:

Code:

---

[Setup]
PrivilegesRequired=admin

---

It is in there?? Already..

I am just learning about this myself but one thing I notice:

Code:

---

OnlyBelowVersion: 0,6

---

...means only if o/s is older than Vista/Win7

The most recent INNO defaults to onlyifnewer anyway (meaning it will not replace an existing and newer system file) so try removing that part of the code (ie... )

Code:

---

.....dll"; DestDir: "{sys}"; Flags: restartreplace uninsneveruninstall sharedfile...
