If you plan to distribute your solution we highly recommend the iMacros Enterprise Edition which includes free unlimited player licenses for use inside your company.
For distributing the Player outside your company you can purchase the iMacros OEM Player separately. The OEM Player allows unlimited, royalty free distribution to anyone (outside your company, web downloads, etc.).

The difference between Enterprise/Standard Editions and the iMacros Players
is the missing recording feature.

Player License examples:
Question: I want to set up 12 PCs at twelve locations to monitor a WEB application and upload response time data to a central database. What license do I need to order?
Answer: You only need to order one iMacros Enterprise Edition license to create (record) the macros (Note: This assumes that you do all the recording on one machine). To replay the macros on your monitoring servers you can use the free iMacros Enterprise Player license that is included in every Enterprise Edition purchase.

Question: Am I able to run the player concurrently?
Answer: Yes! Technically there is no limit in the number of Players that can run concurrently. The number is only limited by the memory and CPU resources of your machine(s). As a rule of thumb, you can open as many iMacros Player instances as you could open Internet Explorers instances on a given machine. From a license point of view, you can run an unlimited number of iMacros Players on the same machine at no extra charge (it counts as one license only).

Question: I integrated iMacros with a C# program. The C# program creates the imacros scripts on-the-fly inside the C# program. Can I redistribute iMacros with my program?
Answer: Yes! You only need to purchase one iMacros Player OEM license and can ship your program along with a copy of the iMacros Player to your users. Alternatively you can even bundle the iMacros runtime files directly into your installer. Alternatively, if you want to embed iMacros inside your .NET program and have full control over the user interface (no iMacros GUI or branding) use the iMacros .NET Browser Control Component.

Question: I have only two developers but users are scattered in different countries like USA, Canada, China, HK, Singapore, etc. After development, can I distribute the scripts to all these users via the 'Unlimited Users iMacros Player License', or do I have to buy and keep at least one iMarco Enterprise Edition version in each country?
Answer: If both your users are within the same company or subsidiary a two user Enterprise Edition license and the free Enterprise Player for all other iMacros users is sufficient. If the users are external to your company or you also need one iMacros Player OEM license to - package your program along with a copy of the iMacros Player to all your users.
