trying to install rhino 4.0 on windows 7, new machine, lots of memory.
'error 1723. there is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. contact your support personnel or package vendor."
tried to run compatibility through properties, but there are no previous versions of windows in the mode list.
also, cannot install previous versions of W installer.
Could be an issue with rhino or possibly a windows deal. Do other programs install alright? If so, give this a try (got it from MS technet).
"If you do have issues with installing other applications via the Windows installer, open up an elevated command prompt and type SFC /VERIFYNOW. Wait out the scan. When finished, do a SFC /? to see the available actions you can take."
As usual with Windows 7, it is a problem with UAC. open UAC, set to minimum level, reboot machine reattempt rhino install as administrator. then it is up to u to leave UAC at that level or reset to default.
