Have you rebooted the machine after removing v16.

Try disabling any anti-virus

What operating system are you using

I'd give the following a try:

1. Make sure the OS is fully updated.
2. Re-download the 3CX v18 Windows Installer from the new partner portal.
3. Run the installation as administrator.

Hi

We had to install this before hand and it installed with out a problem.

 

[Trevor_Couper]

Thanks for the above, we did install version 14.30.30704 before installing version 18.

Thanks for the above, we did install version 14.30.30704 before installing version 18.

So is this sorted for you now after installing C++ runtimes?

To clarify, the 3CX Installer actually installs these:

We got the same issue, is it possible that 3CX installs C++ after the initial install? So first v18 and then the updates on C++? Because the error is received before 3CX can install the update on C++.

Does installing the above manually also fix the issue for you too?

 

[VoiceKing Support]

Can't answer on this yet, still need to try. Will defently give feedback once we did.

I uninstalled the MS Visual C++ version 14.30, installed the 14.24 version (supplied by 3CX support) and v18 installed as expected.

It would appear that there's a dependency in version 14.24 that's not in 14.30 of C++

 

[NickD_3CX]

I have tried a couple of times to replicate this using these versions that you said, The cleanest machine I could find was this one:


Even though nothing else was installed, the latest V18 U2 installed of 3CX for Windows ran just fine, so not sure why it happens in some cases and not in others.
It could be just a case of starting with a certain version in the past, then as Windows Updates update this, something gets "lost".

It is good at least to know it can be resolved by downloading and re-installing the C++ Visual Redists, but I think it would work even if you re-install the latest ones, at least when I tried it a couple of times it worked with 14.30 which is the latest I could find right now.

Had an older visual c++ (2013) and the new (that 3CX installs) but kept getting an error in the end. The solution was to delete the older version. After that no issue occurred.
