Questions and Answers - Fall 2015


Question: I’m having a problem on Micro-Cap. I came out of the component editor and I lost the Analog Models, Analog Primitives, etc…under “Components”. I went back into Components Editor and I can’t figure out how to get it back.

Answer: You have probably deleted the Standard.cmp from the Component library hierarchy. Here's how to fix it. Invoke the Windows menu / Component editor. Use the File Open icon to open the Standard.cmp file, which should still be there in the main Micro-Cap folder. After opening the file, you should see the standard.cmp shown in the library hierarchy list to the right.

Question: We are trying to use the Check for Updates feature to update our Micro-Cap 10. When we attempt to use it we are getting this message:

File update failed

Uncompress: Can’t open c:program File (x86)\Spectrum\MC10\dlmcapver.exe What are we doing wrong?

Answer: Most likely you are attempting to operate out of a folder that is write-protected. You can get around this in two ways:

1) Obtain administrative privileges (usually from your IP department) which allow you to both read and write to Micro-Cap folders. The problem with this is that your admin privileges may be revoked- at any time by IP "maintenance updates".

2) Install Micro-Cap in a folder that is always writable, something like C:\MC10. This is the recommended approach.

Micro-Cap must be able to write to all of its folders, including the main folder (where the Micro-Cap executable is), the DATA folders, and LIBRARY folders.

Note that the c:\Program File.. folder choice is always a bad one as it is always write-protected.

Question: Does Micro-Cap work under Windows 10?

Answer: MC8, MC9, MC10, and MC11 work in Windows 10.
