Hi, I am a Premium member trying to update to EN v. 4.5.8 Public (Build 267864) on my PC (Windows XP). I've tried about three times, and the same series of error messages occurs each time. The file downloads and goes through all the usual steps preparing to install, then balks: 1) "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'Evernote.msi' in the box below." I search for the file, find it, re-enter the path, and click OK. Note: I am not on a large network. There is only one other computer networked to mine, and it is usually off, so it's highly unlikely the file could have gone there. 2) "The file C:\Documents and Settings\Administrator\Local Settings\Temp\Evernote.msi is not a valid installation package for the product Evernote 4.5.7. Try to find the installation package 'Evernote.msi' in a folder from which you can install Evernote v. 4.5.7." Note that the error message thinks I am trying to install 4.5.7. I have EV 4.5.8 (Build 267728). I click OK. 3) "The older version of Evernote 4.5.8 cannot be removed. Contact your technical support group." I click OK. No other choice. 4) "Setup error (.\Bootstrapper.cpp:886) 0x643:Fatal error during installation." Can someone help me? Am I doing something wrong? Should I just wait for the next version to come out? Thank you in advance!
