This post is old but the problem may persist for you, so, in my case, my PC is a little slow and I realized that sometimes FreeFlow Core 6.0 simply does not load and there is no effect trying to restart the FreeFlow Core or SQL services, that is, sometimes I have to restart the PC and wait for it to work the next time. What solved for me was to increase the Windows "service startup timeout" so that it waits longer for the services to start, because if a service does not start within a certain time, Windows kills it and records it in the event log. I think it´s because my PC is a little bit "old and slow".
Bellow are the instructions to modify the registry (https://support.microsoft.com/en-us/help/884495/event-id-7000-appears-in-the-system-log-and-the-isa-...)
To increase the service startup time yourself, create the following registry entry:
Subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
Name: ServicesPipeTimeout
Type: REG_DWORD
Data: The number of milliseconds that you want to give the services to start in.
To create this registry entry, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
Right-click Control, point to New, and then click DWORD Value.
In the New Value #1 box, type ServicesPipeTimeout, and then press ENTER.
Right-click ServicesPipeTimeout, and then click Modify.
Click Decimal, type the number of milliseconds that you want to wait until the service times out, and then click OK.
For example, to wait 60 seconds before the service times out, type 60000.
Quit Registry Editor, and then restart the computer.
PS.: IN MY CASE I CHOOSE 120000 AS VALUE BECAUSE I WANTED 2 MINUTES. YOU CAN TEST CAREFULLY WITH OTHER VALUES.
