When RoamerWorld is installed it performs the following operations: 1. It creates a folder called RoamerWorld2 in the 'Program Files' folder. (You are given the opportunity to change this location if you wish.) 2. It creates a series of sub-folders below the RoamerWorld2 folder (approximately 14 MBytes-worth of data). 3. It registers the following file types: '.rwp' "RoamerWorld Project" and '.gop' "RoamerWorld Go Program" RoamerWorld does not do any of the following: a. Attempt to install or replace any system files. b. Attempt to install or replace any files outside its own installation folder. c. Attempt to install any 'updated' Microsoft components. RoamerWorld is a completely self-contained Win32 SDK program. It is not dependent on Visual Basic or MFC for any of its functionality. (RoamerWorld 2 can be 'installed' simply by dragging a copy of the RoamerWorld2 folder from one computer to another - and then manually registering the .rwp and .gop filetypes if necessary).

What are the differences between RoamerWorld 1.x and RoamerWorld 2.x?


What are the differences between RoamerWorld 1.x and RoamerWorld 2.x?

RoamerWorld 1.x was written a long time ago (when Windows 95 had only just been released) and was designed to support users of Windows 3.1. Most people these days are using Windows 95 or above (i.e. Windows 98, ME, 2000, XP, NT 4). RoamerWorld 2.x is designed for these new operating systems. The main difference as far as the user is concerned is the use of 'long filenames', meaning you can give your projects names such as "My Spaceship Project" rather than being restricted to the 8.3 format of Windows 3.1 (e.g. the above project name would become 'myspac~1.rwp' (8.3) in RoamerWorld 1.x running on Windows 95 or above). All other 'front end' features are the same.

When printing the Graphics Window (Floor), the printout is a solid black square that fills one quarter of the page. (The GO Listing prints correctly.)

Try printing at the lowest resolution that you can set for your printer. For example, if you are printing at 600dpi, try setting this to about 150dpi if your printer options allow this.

I can't open the Activities


I can't open the Activities

The error message, "The specified project could not be found. A default project will be created instead" is displayed after selecting an Activity. Version 2.1 of RoamerWorld does not correctly open Activities if the user's Home Folder (My Documents Folder) is mapped to a single drive letter (e.g. H:). Version 2.2 fixes this problem. Very shortly, a small update patch will be made available that checks your version of RoamerWorld and upgrades automatically to the latest. Please check back shortly.

I'm having problems with the serial interface.


I'm having problems with the serial interface.

+ Check that you are using the correct serial lead (it should have a 2-inch square grey box halfway along the lead). + Check that you have selected an available com port. Try selecting a different com port (use the Settings menu). + If you use a "whiteboard", check that it is not holding open a comm port unecessarily (i.e. when not in use). + Some laptop users have reported that RoamerWorld does not Upload and/or Download to the Floor Roamer. Sometimes the Roamer will beep continuously when connected to the comm port (even if RoamerWorld is not running). (This is currently being investigated. An update will be made available shortly).

Does RoamerWorld 2 use the 'My Documents' Folder for each user?

This means that, when used on a network, the user has access to their work from any workstation. Note: Users with Windows 95 should have Internet Explorer 4 (or above) installed to take advantage of the 'My Documents' folder.

Can I use graphics that I downloaded from the Internet?


Can I use graphics that I downloaded from the Internet?

Most graphic files found on the Internet are JPEG, GIF or PNG format. RoamerWorld uses Windows Bitmap (BMP) files. If you want to use other graphics files, convert them to 'Windows Bitmap' files (with a .bmp file extension) with a paint program. If you use a 256-colour display on your computer, you may find that the colours in your new graphics don't look right
