VI_ERROR_RSRC_NFOUND error after Signal Studio Installation

$

Hello

 

We have 14 test tables in a measurement LAB and every table has a PC running LABVIEW and also GPIB ENET/1000 for GPIB devices. I install Agilent VSA software and also Agilent IO Libraries. Agilent VISA is installed as secondary VISA. There was no problem before installing Agilent Signal Studio Softwares. During the installation, installation manager says that it has to stop NI Configuration Manager, NI Device Loader, NI PXI Resource Manager and NI Variable Engine Services to continue the installation. I made it OK and after installation I restart the computer to get the NI Systems working again and check them in Control Panel > Administrative Tools > Services. They are working too. But after the installation when I opened NI MAX I got "No VISA resources found" error at Devices and Interfaces section. NI VISA can not detect COM1 port now. PCs that I do not install Signal Studio can detect COM1 via NI MAX. At the attachments there is screenshot showing the error.

 

So the problem becomes after Signal Studio Installation. I try to restart NI services, install new 5.4 version NI-MAX (we are using 5.3 version now) but these did not solve the problem. NI VISA 5.1 is present now in PCs. How can I fix this problem?

 

Thanks.
