Hi,
I just want to share my latest experience with you I have made with a Windows 8.1 Upgrade (upgrade is important here) and Lightroom 5.3.
About a week ago I upgraded to Windows 8.1 64bit (via Win 7 64bit --> Win 8 64bit--> 8.1 as an entire upgrade process to save also all of my apps, which were lost without the intermediate step using Win 8). This was the first time I made an upgrade instead of a clean install. Everything worked fine, upgrade went +/- smooth, I saved an enormous bunch of time compared to a total new install.
Yesterday however when I worked with Lightroom--it was not the first time using LR after the upgrade--two curious things came up:
1. LR 5.3 was not able to copy and paste image settings
2. LR 5.3 did not read the printer drivers settings properly, except of the paper size eveything was ignored
I "solved" the first problem by reactivating LR 5.2, which did the job without problems. It even solved the problem for LR 5.3 which was now able again to do as intended.
The second problem again was not existing for LR 5.2, which read all the driver settings and let me make the print as intended. In LR 5.3 the problem was also solved for the printing presets I had just corrected in LR 5.2, but did not solve the problem in general.
What did I do? I re-installed LR 5.3 which now seems to work properly again.
There is nothing / nobody to blame here. Just in case some of you might entounter similar problems after having upgraded to the latest Windows OS this might be helpful.
