Windows Server 2016 Install - BW-PC5 - Error 0x80300024

I tried to install Windows Server 2016 on
BW-PC5
Fujitsu P957.
128 GB SSD.

Install Windows Server 2016.
Choose the hard disk to install, I got the message
Error 0x80300024

To create a partition on the SSD produce the error 0xe7d8f710

I did the following.

1. Unplug all additional had drives (in my case a 1 TB Hard drive)

2. Windows install program, go to repair
command prompt
diskpart

list disk
select disk 0 (in my case the SSD is number 0)
list part
select part 1 (I had 2 partitions)
delete part
select part 2
delete part
clean (very important this deletes the mbr partition table)

Restart the windows installation program

Choose Custom installation.

Create the partition on your SSD.

Successfully install Windows 2016 on SSD.

I wrote a program in Python (2.7 and 3.x). 
This program measure all files beginning with 'GUS' and ending with 'png' in the actual folder. 
Write the result to a file.

echo "list jobtotals" | /opt/bacula/bin/bconsole | grep -i tu-xxx
echo "list jobs" | /opt/bacula/bin/bconsole | grep -i tu-xxx
  (you get jobid, first column)
echo "list joblog jobid=xxxxxx" | /opt/bacula/bin/bconsole | grep -i tu-xxx

Start Restore:

  Start bconlole
/opt/bacula/bin/bconsole
  Now you are connetet to bacula server. Prompt is *

Chemstation on Windows 10, 64 bit

Basically I followed the instruction of Jim Beach

http://jbbeach.com/files/Chemstation/Installation_of_ChemStation_on_64_bit_Windows_7.pdf

Install on Windows 10, 64 bit
Agilent ChemStation Rev. B. 04.01 SP1

• Install Microsoft .NET Framework 3.5
• Install Chemstation Software from Install CD
  run setup.exe in XP compatibility mode
  Path is c:\

To run 64 bit I used the CorFlags.exe from Microsoft SDK  NetFx 6.6.2 Tools.
This path is used
C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.2 Tools\CorFlags.exe
Maybe for you a different path.

• Open Command prompt with Admin rights
• for %A in (C:\Chem32\CORE\*) do ("C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.2 Tools\CorFlags.exe" %A /32BIT+)
  
  Hint: not all files are working, maybe you get the message:
  corflags : error CF008 : The specified file does not have a valid managed header

Start ChemStation
Add Instrument wizard will opened and you can add the devices.

If you want to use an old installation, last action is to copy the old profiles.
Copy the folder "1" to C:\Chem32. "1" stands for your device 1.

When I closed the ChemStation program I got the windows, "program is not properbly closed". No idea how to get rid of the window.
