Upgrade to VeeamBR 12.3.2.4165_20251006 failing

[AlexLeadingEdge]

I've mounted the ISO as normal, it asks me if I want to Modify, I say yes, then it throws up this error message:



I'm also seeing the same with the latest Veeam Agent (VeeamAgentWindows_6.3.2.1302):



Why is it not upgrading? Am I missing something???

//edit: I forgot to mention I'm upgrading from VeeamBR 12.3.2.3617

I had the same issue with the full iso. Using the much smaller patch iso worked.

We should change that error to "Failed to read documentation"
