Please don't embed those CABS... If I ever saw a MSI that huge I would not install it. The MSI's get cached for uninstallation (%SystemRoot%\Installer), but aren't a valid media source for repair operations. As such, your chewing up 2+GB of disk space only for the MSI DB.

Subject: [wix-users] error code 2755: unexpected error installing this package
I need some help with Wix Toolset Installer, We are using Wix Toolset for more then a year.
We are using version 220.127.116.118, I use this with Azure Build Pipeline.
We started getting "2755" on some of the packages at random, when we observed the cause it looks like when the package size reaches 2GB we get this error. I tried to generate the install log. I am attaching the log with this email. I could not understand the cause for the error from the log.
Here is the error from Log
"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755. The arguments are: 110, D:\SVXR\SetupVersions\master_1.4.8.09223_1972\InspectionSetup\InspectionSetup.msi,
MSI (c) (50:2C) [18:09:50:110]: Product: Inspection -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755. The arguments are: 110, D:\SVXR\SetupVersions\master_1.4.8.09223_1972\InspectionSetup\InspectionSetup.msi"
I did some google search and tried all the possible options, that did not help.
In the past, a year back, when we did not use the python harvester, I could create setup for approx. 5 GB size and it was working.
I am using <MediaTemplate EmbedCab="yes"/>
With this option cabs will be added as needed and I don't have to explicitly split my package in to cab files.
Then I saw one documentation page where it mentions that max cabs can be 999 and each cab files size defaults to 200 MB. Which limits my msi package size to 199,800 MB and I guess this is my scenario.
To extend the package size I used WIX_MUMS environment variable and I set that to 300.
Here are my questions:
1. Is my understanding correct on size limit that it can not go beyond 199,800 MB without changing WIX_MUMS?
2. What is the max limit for Wix_MUMS and my package size?
3. How was my previous package in the past building 5 GB and still installing successfully, is this package size limit recent update?
4. Do you see any other issue through my install log?
5. When I build the package using same script through command line, package size was less then the limit 199,800 MB, does packaging using azure pipeline adds extra weight to package size?
Please let me know if you need more information.
