Win 7 register OCX problem

Hello

I have the following problem
registering a control (cwui.ocx) from commandline works

via NSIS only If I remoe the "RequestExecutionLevel admin" entry
codeexample:

!include Library.nsh

Name "test_ocx_install"

OutFile "test_ocx_install.exe"

InstallDir $DESKTOP\Example1

; Request application privileges for Windows Vista

RequestExecutionLevel admin

; Pages

ShowInstDetails show

Page directory

Page instfiles

Section ""

  SetOutPath $TEMP

    !insertmacro  InstallLib REGDLL 0 REBOOT_PROTECTED "..\common\binaries\system32

cwui.ocx"      $SYSDIR\cwui.ocx  $SYSDIR

    ${If} ${Errors}

        DetailPrint "Instlib failed"

        ClearErrors

    ${endIf}

SectionEnd

This one failes
if I remove the RequestExecutionLevel admin or replace it with RequestExecutionLevel none, the register task works well?!?!?


Some hints what I'm doing wrong?😕

I have the same code (has worked perfectly for years) and now I too am getting customers reporting they install my app and get an error about "RICHTX32.ocx" not being registered.

When I get my customers to run the RegSvr32 command it works and they can then run my application.

I'm not sure about taking out the "RequestExecutionLevel admin" - does that seriously work as none?

Even if I reproduce and confirm it is a workaround I would prefer to look into why the standard command doesn't work with admin? You know it would be a hack to detect the OS is win7 and have a condition to lower the privilages to none upon executing the !insertmacro InstallLib REGDLL

This is really frustrating me because we've had win 7 users for a while now and all of a sudden 3 reports in as little as 5 days. Any help would be much appreciated. TIA

Sorry but we still haven't found a solution to this problem!

Thats not 100% right, the newest version of this control don't have this problem, so we gonna update it

The last workaround would be to do pack the control in an MSI file and run it from the installer.
