Tune Sequence Command not working for High Efficient Source (HES)
If you already use sequence commands in MassHunter Revision B.07.06 to automate your daily work, you may run into an error message, if a HES source is installed in your MSD and a TUNE command is executed from a sequence line. To tune a HES source, the correct syntax for the sequence keyword and other parameters is shown below. Running this sequence will generate an macro error that the "do_thor_tune" command could not be found. "Thor" is Agilent's internal alias for 5977 MSD's with the HES option. On the other hand, a manual executed HES tune from inside the tune view menu will work perfectly.
The failure is related due to the fact, that the order in which macros are loaded in the TUNE VIEW is different from the macro order for sequence keywords. In sequences, the required commands are loaded from the file keywd7x.mac and not directly from the definition file seqkeywd.mac. In this case an entry for the HES_ATUNE keyword is missing there.
You can download the revised keywd7x.mac and seqkeywd.mac files for MassHunter B.07.06 here. The files will replace the original versions inside the ..\GCMS\MSEXE directory. Please rename or copy the original macro files before you made the modification. After restarting MassHunter the sequence tune keyword should work as suggested.
Start-Up Message Box for default PDF Printer
You are saving paper in your lab and set therefore the Windows System default printer to a PDF printer driver like the Adobe Acrobat software or other PDF creator packages. Everytime you start up MassHunter now, an annoying message box pops up, informing you that "Windows default Printer is a PDF..." type of printer, which you already know of course. But MassHunter interrupts, its even not fastest loading, while waiting for an acknowledge from you to click OK. This feature could be real boring.
Their is an easy way to get rid of the dialog box without changing original macro files, by only add an entry into the msdchem.ini file. Locate the msdchem.ini file in the ...\GCMS\MSEXE folder and open it with Notepad. Directly under the [PCS] section at the top of the file, add a new line and enter the string "PDFprinterOK=1" like shown in picture. If this entry already exists, change its value from 0 to 1 to disable the check. After saving the file, no info dialog box will pop up again next time starting MassHunter.
Windows™ related fixes
Failed to Connect "Group Policy Client Service" Windows 7 x64
This error pops up everytime during boot or after a login process. In general there are two possibilities for this error and both are related either to a corrupted ntuser.dat file for the logged in user profile or to a corrupted registry entry for the SVCHOST service. Usually, a corrupted registry is caused by Windows updates and upgrades that might mess with the registry. A bad shutdown, startup process or power failure can also cause this issue. If you are already able to login into your account why this error message pops up, there is a big chance that only some registry entries are missing. In this case you should follow Method A. For corrupted user profiles follow Method B.
There are two places to look in the registry:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services this path should contain gpsvc key (a folder), which is responsible for service parameters and configuration. If you found that the key is intact, you do not change anything here - just check that the key exists.
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SVCHOST This is the most important path you should look into, as it must contain the keys and values referred in the key #1. Below are descriptions what must be present there.
- There must be a Multi-String value called GPSvcGroup. If it is missing, you should create a multi-string value named GPSvcGroup and assign a value GPSvc for it.
- Next, you must create a key (a folder) and name it GPSvcGroup - this key normally should be there, but again, it is missing often too.
- Then open the newly-created GPSvcGroup folder and create two  DWORD values:
- First one is called AuthenticationCapabilities and you must give it a value of 0x00003020 (or 12320 in decimal)
- Second one is called CoInitializeSecurityParam and it must have value of 1.
Once completed all steps above, reboot the computer and the problem will be fixed. If you are unfamiliar with registry settings you can download the gpsvc.reg and SVChost.reg files and/or look at the video walkthrough. This fix was first published by SQL-ER at technet.microsoft.com.
Before getting started, you need to log on to your computer with a working administrator account. Then follow the solutions below to fix the problem for your affected account. If you have only one local Administrator account, create another account with administration rights first and login under the newly created account.
- Turn off hide hidden files and hide protected operating system folders, open my computer and <Press ALT+T>, click folder options then view.
- Click <Show Hidden Files Folders and Drives> and Untick <Hide Protected OS Files>
- Open the affected users profile folder under C:\Users\[profilename]
- Rename ntuser.dat to ntuser.dat.old
- Reboot the computer and login as the user. A new user profile is generated from the default profile.
