General Trouble Shooting

Vista/Windows 7 problems with DOS programs:
The 64 bit versions of Vista and Windows 7 no longer support DOS programs (e.g. HydroCalc), since DOS is 16 bit and all 16 bit program support has been eliminated from Windows 64 bit versions. The best solution is to run a Virtual Machine running Windows XP, which can run 16 bit programs as well as 32 bit Windows programs.
* If you are running Windows 7 Professional, Enterprise, or Ultimate editions, you can possibly use what Microsoft calls "XP Mode". There are two files to download and may require a BIOS setting adjustment.
* If your hardware won't allow that, or you are using Windows 7 Home Basic or Home Premium, or you are using Vista 64 bit Windows, another free Virtual Machine is Sun VirtualBox
* There are DOS emulators such as DOSBox however running HydroCalc in this box will not allow you to use Windows external programs, such as creating and viewing PDF files, creating a graphical water flow curve, or using Windows printers.

If you can use Microsoft's XP Mode, then that is probably the more seamless way to proceed. The Sun VirtualBox will also work, but will involve more setup (you will need to install a copy of Windows XP (or any other version of Windows or other OS) from a CD that you own, wheres "XP Mode" includes XP) and you'll need to open the virtual machine prior to running HydroCalc inside that virtual machine. In both cases, you may need to adjust the screen resolution of the Virtual Machine and/or install video drivers onto the Virtual Machine to fine tune the final resolution.

Also, the Sun VirtualBox can be installed onto a Mac and then Windows XP loaded into the Virtual Machine, thus giving even more flexibility.

Installation Problems:

"An I/O error occurred while installing a file. This is normally caused by bad installation media or a corrupt installation file." error message
"Corrupt installation file!" error message
It is possible that your download was incomplete. You probably need to download the install file again. Sometimes your system will cache an existing file and not do a real download of an existing file, so you may need to delete the one from your hard disk first and clear out your cache (Internet Explorer, Tools, Internet Options, General Tab, Temporary Internet Files, Delete Files (and check Delete all offline content), OK). Clearing the Temporary Inteternet Files can resolve many download problems.

Also, Internet Explorer sometimes has problems downloading large files (compare the file size of your download with the size stated on the Download page). If yours is smaller, then you're not getting the whole file. IE versions prior to 7 will not even inform you that there was a problem. You can also read a more detailed description of this problem.
One solution is to add a plug-in to Internet Explorer that does a better job of downloading. One of the best is a free product (or $9.95 for commercial use) by MetaProducts called Download Express or FlashGet which is Freeware.
Another solution is to use a different browser, such as FireFox, free.

"C:\Windows\System32|AUTOEXEC.NT The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application." error message
"Win16 Subsystem was unable to enter Protected Mode. DOS.EXE must be in your AUTOEXEC.NT and present in your PATH" error message
You may need to alter the AUTOEXEC.NT file in your System32 folder (yours may be in C:\WINNT\System32 or C:\WINDOWS\System32 ). You can download the AutoExec.NT file from this web site or the ZIP version and copy, save, or extract the AUTOEXEC.NT to your System32 folder to resolve the problem. Sometimes a reboot is required after altering this file in order for it to take effect. In some cases, you'll also need to install a Config.NT file into the System32 folder which is also in the ZIP file.

"Corrupt installation media detected" error message
This can occur with Windows NT, 2000, XP Guest accounts. Installations are usually installed by an Administrator account who has the right to install executables. Trying to execute an install file from a Guest account may give you a "corrupt installation media detected" error message. If you typically use a Guest account, you will need to log off the Guest account and log into an Administrator account to do an install or update. This will install the program so that it is available to all users. You can then log back into the Guest account to use the program.

Library Problems
The databases used by Calories Made Simple depend on Windows having ODBC installed and it will tell you if it determines that ODBC is not installed. The Windows 98 setup does not automatically do this, although later versions of Windows do. You'll need to download and install all three of the following:
MDAC 2.7 SP1 (5.3 meg)
JET 4.0 SP3 OLEDB (3.6 meg)
Jet 4.0 SP6 (2.9 meg)

Windows XP users: make sure that any shortcut for this application does not have "Compatibility Mode" on. To check, do a right click on the icon, select Properties, and select the Compatibility tab. The top box should NOT be checked.

If you can not start the program because of an Oleaut32.dll error, you will need to update your Windows Operating System. Visit , then scan and install all listed updates. This may also require an update to your Internet Explorer if you have an old version. You may need to repeat the Update process several times, since some updates can only be done exclusively of others.

If you run into a problem because of an RichEd20.dll error, you will need to update your Windows Operating System. Download and install (Windows ME, 98, 95) or (Windows 2000, XP). Use WinZip to extract the file to your Windows\System folder (Windows ME, 98, 95) or WINNT\System32 folder (Windows 2000, XP) or wherever your current RICHED20.DLL is located.
