Master Database cannot be accessed

[1cedt]

So I have bought the newest version (12.0) of Multisim for Academic versio for almost a month. I have never been able to properly used this software. The first installation was working fine, but when I tried to build my circuit design, it turned out that many OpAmp components were missing (eg. TLC277). I spend a couple hours Googling to find whether there were anyway I could update my components database with no luck.

After a few reinstallations and update to 12.0.1, this software simply stoped working. The error message of missing Advance database pops up everytime I start the software. So I proceeded to search through a few forums and found out there were some registry posted as to solve the problem. I tried installing the register many times and I ended up with no luck. I tried to do registry clean up and reinstall the softare again and again. Nothing has worked so far. It's really frustrating. I'm hoping if there is any solution at all.

I am using windows 7 64-bit ultimate dual boot on mac bootcamp.

Hello 1cedt,

This link has .pdfs that show the components available for each version. Are you using Education edition or Student edition? The Education edition includes the TLC277 part while the Student edition does not.

Thank you,

I have the student edition. I guess that is one of the reason why I could not find that component in first place.

I might be wrong. I just don't why they limit such basic component for student. It is one of the reason I need to purchase the software in the first place.

I have friends who install previous version of the software with all the needed components.

Yet still, that does not solve the problem I am having. For, the software itself can't even access the master database

("Problem: Accessing the database.The Master Database cannot be accessed. Features using the Master Database will not be available.") ,meaning it is practically unusable.

Thank for your response.
