Hi Nick,
thank you for quick response! It looks like R.4.1.2 misses the required package of 'BiocManager'. Here are what I did this morning:
1. uninstalled all R-versions (including rTools, R-studio) from control panel
2. deleted R-folder in documents
3. Skyline (version: 21.2.0536)-->tools-->Tool store-->MSstats
4. computer tried to install R-4.1.2 with warning of "A full R installation requires administrative privileges, and it appears that those are not available. if you continue with this installation, you will not be able to associate R with .RData files. Installation must be made to a directory where you have write permission".
5. So I cancelled the installation and installed R.4.1.2 as administrator
6.R.4.1.2 was successfully installed
7. back to Skyline -->tools---> tool store-->MSstats
8. it run for a few seconds and stopped with error message (see attached screenshot) and message below:
on error message (more information) panel:
