During installation, "The system cannot open the device or file specified" error message occurs"


CATEGORY

ASComm.NET

 

SYMPTOMS

Applies to ASComm.NET, ASBrowse.NET, and OPC Servers

When you try to install ASComm.NET, ASBrowse.NET, or an OPC Server, you receive the following error message: The system cannot open the device or file specified

 

CAUSE

This behavior occurs because the Temp folder and possibly other folders used during installation are encrypted by using the Encrypted File System.

 

RESOLUTION

Refer to related Microsoft Knowledgebase article:

http://support.microsoft.com/kb/318080

The following directories need encryption disabled during installation

1. Directory where you saved the downloaded setup.exe file
2. C:\Temp
3. C:\Program Files\Automated Solutions\

After installation, it is okay to enable encryption.
