(I'm specifically troubleshooting an issue with Appeon 6.5 and Appeon 2013 R2, but I'd be curious to know the answer for newer versions as well.)

Is it possible to change the location where the Appeon Xcelerator plug-in is installed on the end-user's PC when running an Appeon Web / PowerServer Web application?

Whether installed automatically or manually, the plug-in tries to install itself in

C:\Windows\Downloaded Program Files

I've run into a situation where the user's access to this folder is restricted, and it would be helpful if the plug-in can instead be automatically installed in


Can this be done?

Hi Ronnie,

For Appeon 2013 and before version, please try solution below.

Step 1: Supposed that the URL you are using to access the AEM of the Appeon

server is, then you can access to the related

plug-in with the following URLs.


Step 2: Extract the weblibrary.dll and the ceondownloadcenter.dll from the

above .cab files and copy them to the client machine, for example C:\ disk.


Step 3: Register the dll files in the Windows Prompt window (you can create

the bat file with the content below). For example, run:

regsvr32 C:/weblibraryxx.dll -s

regsvr32 C:/ceondownloadcenterxx.dll –s

Hi Ronnie,

C:\Windows\Downloaded Program Files is a system folder for Internet Explorer, it is its repository for ActiveX controls.

The good news is, as far as IE is concerned, newer versions of Appeon (PowerServer) have moved to C:\Users\\AppData\Local\Microsoft\Internet Explorer\Downloaded Program Files. So you don't have access restrictions.

All other browsers instead have the PowerServer plugin installed under C:\Users\\AppData\Local\Appeon Multi-browser Plug-in.
