SYMPTOMS

When you install Microsoft Active Directory Services Interfaces (ADSI) version 2.5, you may receive the following error message:

Incorrect INF file syntax in section 'CheckForPrevVer'

Back to the top

CAUSE

The error message occurs when you try to install the wrong ADSI 2.5 binaries for an operating system or when those binaries are from an earlier version.

Back to the top

ADSI has a different set of binaries for Microsoft Windows 98, for Microsoft Windows NT 4.0, and for Microsoft Windows 2000 operating systems. These sets are not interchangeable. The error message that is mentioned in the "Symptoms" section occurs most frequently when you try to install the Windows NT 4.0 version of ADSI on a computer that has either Windows 2000 or Windows 98 installed.

The error message also occurs if the Windows 2000 Active Directory Service Client Extension (DSClient) is installed on a computer that is running Windows 98 and the correct operating system version of ADSI 2.5 is installed afterward. In this case, the version of the ADSI run-time files that is installed by the DSClient is later than the version that is installed with ADSI 2.5.

MORE INFORMATION

The ADSI run-time file is included as a system component in Windows 2000. It is not necessary or supported to separately install ADSI on a computer that is running Windows 2000.

The correct binaries should be installed according to the operating system. When you install ADSI 2.5 for Windows 98, the installation process is completed on a Windows NT 4.0 system without an error message. However, when you try to use ADSI, you receive the following error message:

"Dynamic link library RADMIN32.dll could not be found in specified path"

Versions of ADSI earlier than 2.5 may not correctly scan for existing installations. Therefore, ADSI may incorrectly install over later versions.
