posting again - problems writing to the registry

[muffi78]

Hi,

I am using the software to an interface has a button that basically runs the following actions. It checks to see if a certain plugin is installed on the users system before launching a web page. If the plugin is not installed, it copies the file on to the users system. It runs into complications on IE. On certain versions of IE, registry changes need to be made. If the program is unable to write to the registry, it shows a custom error.

In our testing we found that on different OS with IE 6.0 no updates, the program gives the error message. I have not been able to figure out why it gives the error because the exe is run with administrator privileges on NT like systems and I do not know why it gives the error on 98.

Can anyway please help me? Does anyone know why the application is not allowed to access the registry.

Thank you,

muffi

Try using the plug-in manufacturer's distributed installer.

Corey,

The problem is that my company developed the plugin. And we want to use Auto Media Studio as an installer.

Are you sure that the registry key that you are trying to write to exists on all of those systems? What OS does this error occur on? Does it occur every time that the application is run or is isolated to certain machines? What type of registry value are you trying to create?

Yes the key does exist on all systems. The error occurs accross 98, 2000, ME and XP.

There are three registry entries the application modifies or creates.
It creates the following key if it does exist
Hkey_Classes_Root\MIME\Database\Content Type\x-data/hlq-type

The following value is added to the above key
CLSID = {06DD38D3-D187-11CF-A80D-00C04FD74AD8}

The following value the application modifies to 20(32) if its different.
Hkey_Local_Machine\Software\Microsoft\Internet Explorer\ActiveX Compatibility\{06DD38D3-D187-11CF-A80D-00C04FD74AD8}
Value: Compatibility Flags
