(Be sure to apply PU 8 to your v4.5 step... it's required to be at least v4.5.8 for an upgrade to v2019).

Sage doesn't publish downloads for unsupported versions, but calling support might get you what you need.

Thanks, I already got the link from Sage support.  

The link from Sage isn't working.  Does anyone else have a link I can use to download version 4.5?

I can DropBox it to you, if you still need it.

That would be great.  Thanks!

Uploading now, seems like it might take a little while.

Full disclosure, I couldn't find the original downloaded .exe file so I took a copy of the Installation Files I had on a Backup Hard Drive and zipped them up as "MAS90_200_450.zip". I tested them first and it appeared to be ready to install either MAS 90 or MAS 200 and it pulled the correct keys from my MASREG.INI so hopefully you're good to go.

Do you also need PU 8?

Hi, 

We have a very old instal of MAS 90, it says Version 4. We had a malware attack and lost everything. We do have a backup of the data but need to re-install the server, which we do not have. Can you share the instal files please?

Hi xpankaj, "Version 4" could mean any one of a number of actual versions between 4.00 to 4.50. Open up the Status.flp file using Notepad and see what it says in there. Mine for an old backup of a 4.50 system shows "4.50.1". The file is in the ..\MAS90\SOA folder.

Oh, and of course it is always recommended that you work with your authorized Sage Business Partner on matters such as these.

Thanks. It is 4.05. 

I was given a quote of USD 40,000, hence looking for alternative options.

A backup of MAS90 should be enough to upgrade from.  Get your Sage license in order, then upgrade to a current version.  From such an old version you'd be looking at a multi-step upgrade (which can get tricky) but when it is done you don't have to worry about running your business on ancient software.
