Question

the following code sample works on 99% of PCs

CoInitialize(Nil);

  ScriptControl1:= TScriptControl.create(nil);  

but one user bug report (madExcept) show this :

exception class   : EOleSysError
exception message : Class not registered.

thread $414 (TCreate_restore_point):
004e90b5 +019 xxxx.exe ComObj                   OleError
004e90c8 +010 xxxx.exe ComObj                   OleCheck
0053e668 +04c xxxx.exe OleCtrls                 LicenseCheck
0053e75d +0e9 xxxx.exe OleCtrls                 TOleControl.CreateInstance
0053e125 +125 xxxx.exe OleCtrls                 TOleControl.Create

“ScriptControl1:= TScriptControl.create(nil);” raises an exception “Class not registered”.

How can I register it or solve the issue ?

Thanks

You need install the Windows Script Control in the system in order to use the TScriptControl class.
