Questions and Answers - Winter 2013


Question: We're doing a professional Lan version: Client (Local Files) install. We have a license server that's remote to the local machine that hosts the license. This is indicated in the nethasp.ini file.

I reinstalled it a few times and got the Aladdin device drivers to say they installed. But every time I run it I get an error saying it has encountered a problem and needs to close. This happens right after it reads the ini file and determines there's no hasp on the local machine.

If I set the ini file to the default, it opens and says there's no hasp on the machine and then exits.

I should mention that we are running RDP.

What am I doing wrong?

Answer: The current version of Micro-Cap (MC10) does not support RDP (Remote Desktop Protocol) or any other form of remote terminal services. If you try to run Micro-Cap over RDP it will generate this error. Try running it directly connected and the error will go away. Future versions of Micro-Cap may support RDP.

Question: I am trying to port our engineering client PCs to a new license server where we will be moving our license dongle. I would like to use the server name in the INI file on the appropriate line.

NH_SERVER_NAME = puscwa0d

The documentation says that the limit to the server name is 7 characters. That seems quite small. Is this correct for the INI line, and if so, is there another way of using the name instead of the IP address?

Answer: Yes. It's true. If you use a server name, its length is limited to 7 characters. You can always use the IP address which can be and usually is longer than 7 characters.

Question: We are testing Micro-Cap and we are having a problem saving files on our Windows 7 desktop with the error, "Permission denied C:\Users\username\Desktop\circuit1.cir". We are just wondering whether this is one of the known issues.

Answer: Up until version saving certain files to the desktop in Windows 7 was a problem with both the demo and main program. We have fixed it by using newer libraries for the Save command. Version now allows saving any kind of file to desktop folders.
