Hello Anette,
when trying to solve the problem, did you only re-register the ActiveX Tabstrip itself or the whole MSCOMCTL.OCX the control is associated with ?
I am asking because even if I did not find a directly matching issue for your problem during my Internet research, it seems that in the past every now and then several issues came up such as wrong file versions of MSCOMCTL.OCX delivered, problems in conjunction with Microsoft security updates for Office, change of versions numbers of TypeLibs etc.
Some users were able to solve the problem by re-registering MSCOMCTL.OCX (using admin rights !)
On a 64 bit machine:
Regsvr32 /u "C:\Windows\SysWOW64\MSCOMCTL.OCX"
Regsvr32 "C:\Windows\SysWOW64\MSCOMCTL.OCX"
On a 32 bit machine:
Regsvr32 /u "C:\Windows\System32\MSCOMCTL.OCX"
Regsvr32 "C:\Windows\System32\MSCOMCTL.OCX"
Other users had to first install an older version of MSCOMCTL.OCX, unregister it and then install the younger version to solve their problems. To get more information, do an Internet research typing:
Fixing the Microsoft Windows Common Control Library (MSCOMCTL.OCX) Security Update
Others had to keep the MSCOMCTL:OCX on an additional directory. To get more information, do an Internet research typing :
Office 2019 Pro C2R monthly Update ships wrong MsComCtl.ocx Fileversion
Perhaps the above links can assist you in detecting the cause of your specific error.
Best regards

After an automatic windows update, we get errors in the application.In a function that uses ActiveX Tabstrip, it does not work and there is runtime error.
