3.16 P015 Installation problem

[AMRPatricio]

Hi all,
I did try to update my 3.16 P007 for the latest P015 without success. Having the following error/warning "Error during caching stage". I did try to install the P014 but a different warning was raise. See please attachments.

Any ideas?

BR,

Can you please try if it works when you
-- Deinstall WinCC OA 3.16
-- Check if all files are deleted
-- Install WinCC OA 3.16 P015

Hi Leopold,
the warning "Error during caching stage" it is NOT appearing anymore. However I am having the same warning that I did have before for P014.

If the problem still occurs please check which version of Visual Studio 2015 Redistributables is installed at your system.

Not sure if help is still needed but I had the same problem and and could solve it as follows:

Used Software:
Windows 10
WinCC OA 3.16 P015 (fresh install)

I got the same error message as above. In the log file (mentioned in the error message) I could find the actual error code for the failing software component "Microsoft_Visual_Studio_2015_x86_Redist" (i.e. Microsoft Visual C++ 2015 Redistributable):
0x80070666 - Another version of this product is already installed. Installation of this version cannot continue.

I had multiple version of "Visual C++ 20xx Redistributable" installed on my system, e.g. 2010, 2012, 2013 and 2017.
Deinstalling the newer 2017 version did the trick and I could install WinCC OA without errors.

I also tried installing the required 2015 version manually (without the WinCC OA installer and before removing the 2017 version) but this did not help, so the problem is not related to the WinCC OA installer but possible a Windows problem.

Since it is possible to have multiple versions of "Visual C++ Redistributable" installed it could be a Windows bug, or the different versions have to be installed in order.

Maybe it will help other users: I had similar problem with 3.17 P002, with Visual Studio 2017 to be precise.

Solved it by installing latest Visual Studio Redistributables manually from: https://support.microsoft.com/en-us/hel ... -downloads , before running WinCC OA installation process.

According to my error log, the error code was 0x800704ec , which may indicate problem with Windows Defender not running (blocked by group policy).
