Hi All,
I am trying to install SQL Server 2014 express edition on my Windows 7 64 Bit system, but unfortunately, everything I have tried so far has resulted in the same error.
Error: 1723 There is a problem with this Windows Installer package. A DLL required for this installation to complete could not be run. Contact your support personnel or package vendor.
I have tried all the possible solutions that I found online. So please refrain from posting a link to another blog or forum because chances are that I have already tried that.
Things that I have tried:
- Giving myself/Everyone "Full Control" over the folder C:\Users\username\AppData\Local\Temp
- Disabling .Net Framework 3.5 SP1 and then re-enabling.
- Installing sqlncli.msi manually from cmd with Administrative Privileges (Note that this too fails with the same error).
- Removing all instances and traces (registry values, folders, uninstalling) of SQL Server 2008 R2 installed previously on my machine.
- Downloading SQL Server from Microsoft's website again (in case the previous installer was corrupted), performed checksum and validated the installer.
- Making sure that I have Service Pack 1 installed for my operating system.
- Resetting windows installer.
I am aware that there are multiple threads with the same issue, but none have been able to resolve this for me.
It is really urgent for me to resolve this and install the package over the weekend. Any help would be really appreciated.
Note: I am unable to add the links to the log files as of now, but would do so ASAP.
