Demand loading requiring ACAD.exe Admin rights (.Net Framework version?)

SRSDS — Thu, 23 May 2019 19:35:57 GMT

I'm going to put this out there before testing my suspicion.

I have two apps which both have demand load entries.

One loads on users computers while the other doesn't to unless I start acad.exe with admin rights.

I can only think that the one that works is uses .NET 4.0 while the other is set to .NET 4.6.1.

The coding for demand loading is a copy and paste.

Could the .Net Framework version have any effect on the user's permissions in accessing the registry?

It's also something to do with user permissions granted.

If I log onto the users computer as myself it loads.

I don't know how to give the users the necessary permissions .

Hi,

I do not think it's due to the Framework version, but to be sure you can just try it with a new DLL compiled against a different Framework.

For clarification - are you setting demand-load registry settings when the DLL is loaded? If so, it needs to be done with proper permissions to modify the registry. One of the reasons I don't follow the online examples of doing so - it doesn't work if the user has restricted permissions.

You might get around it by separating out the code to do into a different module, one that can be securely run with elevated permissions once during an install operation. I normally use a REG file and basic scripting for this.

Hi @SRSDS,

Is not been clarified 100% your requirements for me, but as I read your post, some routine of your code has problems to admin rights and modifie windows registry; if is the problem, independly of .NET Version, think about use Impersonation concept under your rotine; in other words, encapsulate your program flow inner Impersonator code, the developer does not have to worry about giving permissions for each user that consumes the app.

This tutorial by Wayne Ye having an explanation about Impersonation scenarios and code example, this helps me.

Att,

Antonio Leonardo.

I apologize for not answering this earlier. Probably good because I would have been wasting peoples time which has already occurred. I only discovered this a day or so ago.

Turns out to be a problem with a third party program which encryptions files (Gemalto Sentinel LDK HASP).

The current version 7.9 does't work and I needed to revert to 7.6.

Very confusing because it was working on some computers and not others.
