(1/6/2021) A new version of the MultiTrace is available now. Version 5.8.x contains a new software patch restoring normal function to the MultiTrace software. This is a significant change to underlying code, thanks to ongoing development for the new generation of DataTrace, we were able to quickly implement a fix and roll out this new version before many customers have been affected. Customers under warranty or who are active in the RTI Software update program may receive this version now for no cost. Other customers are asked to purchase a software update subscription to be eligible for updates, please contact RTI for a download link or to obtain a quotation for the software update.
A bug in a recent Windows update “Windows 10 feature update version 2004” affects all versions of the MultiTrace software. A function required by StdTrace to acquire data has stopped working, it seems like a variable is not reset and the function only works once.
Specifically, when configuring a test using MTForms, the test will run one time normally but then the test will not run again until the MultiTrace software is restarted. Running a test, a second time will result in loss of the first set of curves collected.
Who is affected?
- ALL Users with Windows 10 who keep their computers up to date
- ALL versions of the MultiTrace software
- Win 10 controllers connected to MultiTrace or MegaTrace hardware
- Win 10 users offline use for training
- Win 10 controllers that receive updates pushed from internal IT organizations
- Win 10 controllers that update over the internet
Who is not affected?
- Controllers not connected to the internet or that do not receive windows updates
- Controllers running any version of Windows 7
- Personal Computers and workstations used for analyzing curves offline

At the time of writing, Windows 10 feature update version 2004 is optional and Microsoft is rolling it out slowly to customers using AI to decide who gets it. Optional means it will not appear as an automatic update with a reboot required but requires the user to first go to the update section of settings and presses the “check for updates now” button at which time, this version may become available. Not all users will have this version available.
Windows also lists at least 10 unresolved bugs. While they seem unrelated, there still may be a common windows function to the MultiTrace software and there are likely to be other unannounced bugs. This problem may resolve on its own and if it does, this advice will be revised, and you may be allowed to continue with windows updates as usual.
RTI is working to identify the exact point(s) of failure and patch the code to restore proper function regardless of the status of Windows. Please check our website software status page for current information and recommendations. If Microsoft does not resolve this issue in a future release, you may be required to upgrade the MultiTrace software in order to continue with the Windows Update program.
