SAP GUI 7.70 deletes old OCX libraries

Hello gurus,

I use SAP installation server to make a single file installer for SAP GUI 7.70.

When I upgrade from 7.40 to 7.70 the installer deletes old OCX files.

I supose they are part of old Microsoft Visual C++ Redistributable Runtime.

However they are used in anoter app ot the user computer, so whe I upgrade SAP GUI the other app stops working until you copy those OCX from another PC, and use regsrv32.

How can I prevent SAP GUI 7.70 installer from removing those OCX files??

Thanks

Ilian

P.S.

It deletes Msflxgrd.ocx Mscomctl.ocx Mscomct2.ocx from c:\Windows\SysWOW64 ...
