Error 1931 from Windows Installer Sevice attempting to install scrrun.dll with a VB6 app
Posted on 2004-10-10
Expert help, please
My VB6 app is developed on an XP SP2 machine, and runs properly. It uses FSO extensively.
I use Visual Studio Installer to create an .MSI file. When I run the .MSI file on a Windows 2K machine, I get this error message, which I have never received before despite having done the installation numerous times on the particullar W2K machine or indeed any machine back as far as NT4.
"Error 1931 The Windows Installer Service cannot update the system file C:\WINNT\SYSTEM32\SCRRUN.DLL because the file is protected by Windows. You may need to update your operating system."
I ignore the message, continue the installation, and am able to run the app on the W2K machine without problem. Because the app is distributed to clients, I need to solve this problem before I provide them with the next update.
