Windows 98 Installation Problems

If you have an older version of Windows 98 (First Edition) you may have minor difficulties installing RezStream Professional. This is due to the fact that older Windows 98 systems may lack necessary files for a proper installation of RezStream Professional. To remedy this problem:


  1. Install RezStream Professional and see if it installs completely. You will see our "Preview Screen" at the end of the installation. If you are trying to install RezStream Professional and you are asked to reboot your computer, please do so.
  2. If you think RezStream Professional installed properly but will not launch when you click on the program icon from the Start Menu, proceed to step 3.

  3. If you get the error message "Class Not Registered" when attempting to launch RezStream Professional, try installing the Microsoft Jet4SP3_Comp.exe file that we include in the CD-Rom "Extra" folder.

Problems Opening RezStream Professional

If you receive an error when opening RezStream Professional, please try the following:


1. Repair your database.

2. If you are running RezStream Professional on a network, confirm that the server is available (the server is the computer that holds the database). Use the following steps to confirm that the server is available.

a. Open My Computer, either from the Start menu or from the Desktop.

b. On the left-hand side of the window is the Task Pane, which should have an icon that says "My Network Places.” Select this icon.

c. Look for a folder that says "RezStream on SERVER", where SERVER is the name of the server that holds the database. Open this folder. If you have problems accessing it, then your connection to the network may have failed. Try rebooting your computer or check that the network cable for your computer is plugged in.

d. If you do not see the folder as mentioned in Step 3, then go to the View menu, select Explorer Bar, and select Folders. You should now see a list of folders on the left hand side of the window.

e. Expand the folder titled Entire Network (click on the plus sign to expand the folder). Expand Microsoft Windows Network. You should now see a list of "workgroups" in your network. Expand each one until you see the name of your server. Click on the icon for your server. If you cannot access any folders on the server then your connection to the network may have failed.

3. Restore from a backup.


Troubleshooting a Slow Database

If your database seems slow, please try the following:

  1. Restart your computer. This is particularly important on operating systems earlier than Windows XP. Typically you should restart your machine at least once a day to maintain maximum performance.

  2. Repair your database by running the RezStream Professional File Utility program.

  3. Check your system for viruses and spyware. Use your anti-virus software to scan all of your hard drives for potential viruses. If you do not find any infection or if your anti-virus software is out of date, consider using the free online virus scanner found at:

  4. Download and install an adware/spyware removal utility such as AdAware ( or SpyBot ( If you find any viruses or spyware, consider installing a firewall on your system to avoid any future infections.

  5. Run the error checking utility on your hard drive. To do this, Select Start > My Computer, or go to your desktop and double-click on the My Computer icon. Right-click on the C:\ drive (usually named Local Disk C) and select Properties. Click the Tools tab, and select Check Now. Select the option for "Automatically fix file system errors", but do not select the option for "Scan for and attempt recovery of bad sectors" as this will take a long time to complete and is usually unnecessary.

  6. Run the defragmentation tool on your hard drive. To do this, Select Start > My Computer, or go to your desktop and double-click on the My Computer icon. Right-click on the C:\ drive (usually named Local Disk C) and select Properties. Click the Tools tab, and select Defragment Now. Click Defragment.

  7. Check the specifications of your computer. RezStream does not recommend running RezStream Professional on any machine that is not at least a Pentium 4 with 128MB of RAM.


Troubleshooting Tips for Unit Rates that do not seem Accurate

  1. Make sure that you have entered the correct prices and dates into the seasonal rates lines under each rate. You do not need to use each of the columns but you must have something in the "Rack" column (the column just to the right of your dates). Do not leave any columns blank. If you charge extra for weekends, that column should only contain the extra dollar amount above and beyond what you enter in the "Rack" column. To set what days are weekends, go to the "Options" tab.

  2. Make sure you have the right tax class assigned to each of your rate names.

  3. Make sure that you do not leave empty fields (blanks) in the "Base Cap" column. The base cap is the number of people the unit rate is based on. Usually this is 2 but may be higher for larger rental units. In the Individual Units tab you can then specify what your maximum capacity is for the rental unit. (Example: Base cap = 2, Maximum capacity = 4) The Base Cap column must have something in it for each and every seasonal rate line, for each and every rate name. Look down the Base Cap columns for each rate and make sure there are no blank lines. Do not leave any blank fields in the "Package" column under unit rate names. "None" is fine, but blank is not.

  4. It is better to leave a 0 in a rate field you are not using than leaving it blank.

  5. Make sure you attach the right rate name to the right individual unit.
    (see Individual Units)

  6. Check your taxes. Note that taxes are entered as a percentage, not a fraction. For example, taxes should be entered as 7.5, NOT .075 .


Troubleshooting Internet Connection Problems

The information below applies to any kind of upload/download to the Internet from within RezStream Professional, including online availability, program updates, and database uploads.


  1. Make sure you are connected to the Internet.

  2. If you use a dial-up connection, it is possible that your modem is disconnecting during the download. To avoid this, open your e-mail client and set it to check for new messages every 10 minutes (or less). This setting can often be found under Tools > Options. Leave your e-mail client open while downloading the update.

  3. If you use a firewall, make sure that it is set to allow RezStream.exe access to the Internet on port 80, 20, and 21. If you do not know how to configure your firewall appropriately, you can try temporarily disabling your firewall while downloading updates. Please see the documentation for your firewall for more information.

  4. If you download an update to RezStream Professional, you may receive this error when the update program begins: "One or more files were not unzipped. The error code is 40." This indicates the download did not successfully complete. Download the update again.
