Managed to start it! The trick was to increase the time before timeout is called. The default windows timeout is 30 seconds. Increased it on 2 minutes and all services started from the first time!
To increase this value to 2 mins (120 seconds), follow these steps:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. In the right pane, locate the ServicesPipeTimeout entry. Note If the ServicesPipeTimeout entry does not exist, you must create it. To do this, follow these steps:
a. On the Edit menu, point to New, and then click DWORD Value.
b. Type ServicesPipeTimeout, and then press ENTER
4. Right-click ServicesPipeTimeout, and then click Modify.
5. Click Decimal, type 120000, and then click OK. This value represents the time in milliseconds before a service times out.
Note: 120000 milliseconds (2 minutes) is equal to what the default configuration should be. You may find you need increase this number. 300000 (5 minutes) may be more suitable.
6. Restart the computer.
I had the exact same problem and your suggestion resolved the problem.
Fresh W2012 R2 and install of QS 126.96.36.199, all working fine
Windows Update and server restarted over the weekend, now only two of the services will start.
Made the registry change and now all services will start again.
Also upgraded to 188.8.131.52 for good measure and services all still ok.
I had the same issue on version 3.1.1, the upgrade to the version 3.1.3 solved the issue, but when I tried to restart the services few days after the issue came again.
The upgrade of the DotNet Framework to version 4.6.2 has solved my issue.
