Problem Upgrading from 4.2 Installation files and machine files

Hi

I currently use Pcdimis 4.2 with a Romer Sigma arm. Recently tried installing to the newest version, input the code received from hexagon software installation went well. Problem now is when trying to open the software either the new version or the old as soon as they open I get the blue screen of death. The laptop originally came with the arm from Hexagon and is about 5 to 7 years old. Speaking to Hexagon they reckon our laptop is to old.

Initially I received training from Hexagon on how to use the arm, but this was quite some time ago and would not have been using it on a regular basis, I would not consider myself an expert by any means, I do have many years experience Programming and operating CNC machining centers, I am toolmaker by trade, and have recently received my Degree in Mechanical Engineering.

I have a new position in the company and now need to use this arm on a regular basis however I have never had any confidence in the arms capabilities especially when comparing to know measurements, I seldom achieved exact or values close to actual values, when measured with a micrometer Initially I thought this was due to my technique or approach but I have read that many users have had similar problems that I have experienced.

My initial reasoning to upgrade to the newest version was to address all the bugs and problems with ver 4.2, but now I seem to have made things worse. I know the arm and laptop was recently calibrated and returned from hexagon

So to cut a long story short I have uninstalled the new version and reinstated a last know configuration to get the laptop to open the 4.2 without crashing, what I am not sure of is if this state captures the most recent files stored on the laptop during the recent calibration that was done.

Could some explain to me what files needs to be copied and backed up when doing a software upgrade. I am aware of the probes but are there any others to consider.

I want to check these against the files the Calibration company should have to see if they are the most up to date ones, because after doing simple measurements of know artifacts like slip gauges which would be considered precise. I find that the measurements are out by up to 0.2 when measuring a distance of between the planes set on both sides of the slip gauge

If I get a new Laptop and install the latest version of Pcdmis what files would I have to transfer to the new PC. My feeling is that I would also need the Romosoft or Rom@tic for communication to the arm. Any idea where to get this software and would there be any files to be considered for this aswell.
