Faced no problem yet, updated Nest/NestChart last week.
For everyone who is running ZT as admin / running in compat mode / copying to another path
1) Since Windows Vista, C:/Program files is protected and needs admin rights to modify. Only installation/update files are meant to go here
2) Ideally, program should write any writable/configuration stuff within your home/documents folder in C:\Users. This allows programs to run without admin for most cases.
3) Generally, Nest is Pest, old generation crap that they dont bother to maintain properly. So you face all these issues of having to run as admin.
4) Solution is simply to install it outside C:/Program Files. I put it and nest charts in C:/XXX/Omnesys/Nest and never have to do any of this.
5) Make sure to uninstall ZT and NestPlus before you update.
So, In general install old programs outside C:/Program Files to avoid having to run them as admin.
For once microsoft did something right, but stupid programs make a mess.
can't link to excel
If you ran ZT as admin, then run excel as admin too...
