Unable to upgrade PBI RS from September 2019 to January 2020

[Anonymous]

Hi

I have trouble upgrading our Power BI Report server from Sept 2019 to Jan 2020.

The error message at the end of the install process is: 

"The Temp folder is on a drive that is full or is inaccessible. Free up space on the drive or verify that you have write permission on the Temp folder"

When I analyze the logs it looks like it's about this folder: C:\Users\<MyUsername>\AppData\Local\Temp\

Has anyone else had this issue before ? Or know how to solve it ?

Thank you all in advance for your help

Hi @Anonymous ,

please check the requirements to install/ upgrade the Server: https://docs.microsoft.com/en-us/power-bi/report-server/system-requirements

May be the capacity on you local machine isn't enough to upgrade the new version? Check your capacitiy on you C: drive 🙂

Best,

Kathrin

Thank you @KBO for your response. But all the requirements are met.

After doing some digging, we found out the C:\Windows\Installer folder has been deleted (accidentally) and that what caused the problem. We created it manually and now the Power BI Upgrade works.

Kindly,
