2001i - version 15 compatibility

[garybetts]

I have mathcad 2001i which I am finally forced to upgrade because it won't work on my 64-bit windows 7 computer.

Will mathcad version 15 open 2001i files (.mcd)? If so, will they be usable with minor editing or will there be a lot of work required to get them working right?

(I read that version 15 will not save in 2001i format so it makes me think that maybe it won't open 2001i files either.)

I believe it will open the file but only save down to version 14. I think you would need version 11 to save down to 2001i, but I'm not entirely sure. You could post an example and I'll try opening.

Richard to name one collab has muliple versions - you might want to wait for his reply.

Good idea. I am attaching one of my mathcad 2001i files. If someone with version 15 can open it, it will answer my question.

I have just opened the file with no error messages.

I have attached a few images of the graphs and results tables so you can check if the answers came out the same.

Thanks.

It looks like version 15 opened the files OK and the output format is still the same. (I had big problems with this when I changed from mathcad 7 to 2001i back in 2002 which is why I was afraid to upgrade after that.) I hope you get a commission because you probably just sold a copy of Mathcad 15!

I'm glad it works and your happy. Version 15 is a good version.

I'm afraid not. If you purchase the new product Mathcad Prime you get Mathcad 15 with it.

M15 will save down to M11, Mike. Unfortunately, I've had to remove my M14 so I can't check what version it will save down to, but I'm reasonably sure that M13 would have handled M2001i.

According to version 14's "save as" pull-down menu, version 11 is as far back as it goes.

M15 will save down to M11, Mike.

Typo well spotted, it should have said 11.

but I'm reasonably sure that M13 would have handled M2001i.

Never had the pleasure of using M13, my employer jumped from 11 to 14.

Versions 2001i, 11, 12 and 13 can save to 2001i format. Later Mathcad versions (with the exception of Prime) can always read files created with earlier versions. Although they can always read them, there may be compatibility issues though. Most 2001i files will run in 15 with no modifications at all. Some files will require changes, but usually they are minor. A few files may not run, and may not be fixable at all. That really is a few though, and the problem will be associated with one of only a few things: changes to the way user DLLs work, deprecated extension packs, Static Unit Checking, or the speed of execution of scripted components.

Good post Richard, cheers for clearing that up.
