Find what error happens during file open?
I want to find what error happens during file open for read.
Code:

ClearErrors
FileOpen $R3 "$0" r
${If} ${Errors}
DetailPrint "Error opening file '$0' for read."
${EndIf}
StrCpy $R1 0


Log: (using NSIS with logging)
detailprint: FileOpen $R3 "c:\inetpub\wwwroot\PortalBuilder\App_Data\Uninstall\UILayer.log" r
detailprint: Error opening file 'c:\inetpub\wwwroot\PortalBuilder\App_Data\Uninstall\UILayer.log' for read.

The file
exists
I can open it in notepad and read the contents.

I'm using NSIS 2.36 (And can upgrade if needed)
Other file was opened okay using the same code.

Than you in advance for any response.

You can't get error codes from NSIS functions.
You need the system plugin to call kernel32::OpenFile to get the errorcode.

CreateFile, not OpenFile

but, before you go down that route, you should check with ProcessMonitor/FileMon from sysinternals

Thank you jpderuiter, Anders, you saved my day.

Filemon & Process Explorer exposed I did not clean handles properly when in another function.
