Clarion 12 - What Problems or Issues have you found?

I use a VPS with my internet provider. It has Windows Server 2022 and only SQL Server installed. All ports are closed except those required for SQL Server to work. The connection string contains the IP address or domain name. Everything works perfectly, there are about 50 databases per server with more than 100 users and everything works with 8GB RAM and 200GB SSD.

Thanks.
I try that many years ago but it was slow - browse with 1000-2000 records loads for 5-10 seconds.
I have 280 tables and 20 views.

Re-install fixed it.

Hi,

I’m trying to install clarion 12 on my local computer for testing purposes. I’ve installed all needed dependencies but i still have the following error while launching C12 :

Unhandled exception terminated Clarion

Exception Type: System.IO.FileNotFoundException
File Not Found: clarion.asl.dll
Error Message: Impossible de charger le fichier ou l'assembly 'clarion.asl.dll' ou une de ses dépendances. Le module spécifié est introuvable.

Exception thrown:

   à ICSharpCode.SharpDevelop.SharpDevelopMain.RunApplication()
   à ICSharpCode.SharpDevelop.SharpDevelopMain.Run(String[] args)
   à ICSharpCode.SharpDevelop.SharpDevelopMain.Main(String[] args)

Can someone help me ? I am currently running on W11 24H2.

"all needed dependencies " what is that?

  • as I know there is only vcredist2013_x86.exe needed for clarion
    to work.

I have the file “clarion.asl.dll” in C:\Clarion12\bin. Its 154,112 bytes and dated 4/25/2025

If this is the same error I had (installing C12 PE on a fresh Windows 11 Virtual Machine for testing) I suspect it’s because the Clarion installer does not trigger the install of the required VC Redistributables. Instead of trying to figure out which ones to install, I first installed the latest C11.1 PE release, which did install the VC files, and after that I was able to install, run, and register C12.

Good luck.

New problem, Clarion 12 PE,
when clicking on error after generate, nothing hapens, it is not opening the source editor.

The SoftVelocity C12 installer appears to be missing a redistributable component. As a result, C12 fails with a “System.IO.FileNotFoundException” error on a clean Windows machine. I have created a quick fix for this issue. Simply download and run it on affected machines.
