Error opening file for writing

Hello all,

I am seeing "error opening file for writing" randomly on some of the 64 bit Windows 7 and Vista for one of the dll. Not sure why it only happens randomly.

Here is how I have it:

; at the beginning
RequestExecutionLevel user

; .onInit section
UAC plugin

; Install section
${If} Running_64
ExecWait '"$SYSDIR\regsvr32.exe" /s "$INSTDIR\Namespace.x64.dll"'
ExecWait '"$WINDIR\SysWOW64\regsvr32.exe" /s "$INSTDIR\Namespace.x86.dll"'
ExecWait '"$SYSDIR\regsvr32.exe" /s "$INSTDIR\Namespace.x86.dll"'


Many thanks!

'Error opening file for writing' appears only when a file couldnot be overwritten. You may use the code "SetOverWrite try".
