The 7GR EXCEL + HR2 software was originally tested with 32-bit Office and EXCEL 2003 and WIN XP as well as EXCEL 2007 and VISTA Ultimate 64bit. Since 2021 the Seven Golden Rules are also 64-bit EXCEL compatible, thanks to the .NET DLL of MWTWIN at PNNL [LINK].
Parts of the 7GR software use an older version of MWTWIN. Please update the isotopic mass table to the latest IUPAC recommendations [PDF] or simply check the numbers provided (for ultra-accurate mass measurements). This old version of the 7GR only works on MS Excel 32bits. The 7GR can be used in manual mode (molecular formulas need to be entered) or automatic batch mode which is the preferred mode by entering the experimental neutral mass (without adducts - an adduct calculator is provided), the experimental isotopic abundances, assumed mass accuracy and isotopic pattern accuracy and suspected elements (CHNSOPFlClBrSi). Up to 60,000 experimental values can be calculated in one batch run. One single calculation is usually finished in 20-30 seconds. Due to the overhead by the EXCEL calculations, several thousand values can take hours. The latest version is v46 which contains all the data and validation , the 64-bit update only contains the new EXCEL sheet. Therefore it is recommended to download and extract both ZIP files.
Download Section:
The Seven Golden Rules v46 can be downloaded here as (42 Mbyte, recommended download, contains all data) [ZIP].
The Seven Golden Rules v46 for 64-bit Office update can be found here (10 Mbyte, only XLSM, not all data) [ZIP]
The Seven Golden Rules are also implemented into MS-FINDER you can find the software here [LINK].

Installation issues for the 32-bit version with later Office versions (2003 and up) and VISTA, WIN7 in 64 bit mode, can lead to error messages that certain libraries are not installed. These errors include:
> Microsoft Visual Basic
> Compile error: CanĀ“t find project or library
> strBuffer = Space(dhcMaxPath)
Solution: Make sure all the following DLLs, EXE and TLBs are installed:
(Check EXCEL--> Developer --> Visual Basic --> Tools --> References)
- MWTWINdll.dll
- 2) Microsoft Office 12.0 Object Library
- 3) Microsoft Forms 2.0 Object Library
- 4) OLE Automation
- 5) Microsoft EXCEL 12.0 Object Library
- 6) Visual Basic for Applications
