Questions and Answers - Winter 2014


Question: Does Micro-Cap come with a node-locked or a floating license?

Answer: First of all, a few definitions:

Node-locked license: This is a license that allows the user to install the program on only one machine.Micro-Cap does NOT currently use node-locked licenses. Micro-Cap may be installed on as many machines as desired. However, it will only run simultaneously on as many machines as there are licensed seats.

Floating license: This is a license that allows the user to install the program anywhere he likes. This is the only type of license that Micro-Cap currently uses.

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: Canít 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 "maintainence 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.
