Microsoft Internet Explorer 11.
Intel Core i5 or Intel Core i7 (the 3rd generation).
8 GB of RAM or more.
5 GB of free space on the system disk.
2 GB of free disk space for installation, plus extra space for temporary files during test runs (see below).
1280 × 1024 or higher display resolution, if you use 100% DPI. A larger DPI value requires a larger display resolution.

Minimal System Requirements
Microsoft Windows 7 with Service Pack 1.
Microsoft Internet Explorer 11.
Intel Core 2 Duo 2 GHz or higher.
2 GB of RAM.
4 GB of free space on the system disk.

Disk Space Requirements
TestComplete creates and uses temporary files during test runs. The free disk space required by TestComplete depends on your project size. You need at least 500 MB of free space on the system disk to run small projects, and 1-2 GB of free disk space to run large projects.
Please pay attention to the free disk space before running tests. If your system disk runs out of free space during a test run, TestComplete can malfunction. For example, TestComplete may stop responding to your commands, may not generate test events, the panel layout may get broken, and so on.
To activate a TestComplete license, your computer must have an Internet connection. After you activate the license, the Internet connection is no longer needed.

Running TestComplete on Virtual Machines
Virtual machines like Microsoft Virtual PC or VMware Workstation use a lot of system resources. Typically, applications run slower on virtual machines than on desktop computers. The more virtual machines run on a computer at the same time, the slower they are. To use TestComplete on a virtual machine, use a high-performance host computer that exceeds the recommended requirements to ensure the virtual machine has good performance.
|You need a Floating User license to use TestComplete on a virtual machine. For more information, see Using TestComplete on Virtual Machines.|

Microsoft Office Excel Data Connectivity
|All these requirements must be met if you work with Excel files via DB Table variables,
To use Microsoft Office Excel 2007 - 2013 files in tests, you must have the Microsoft Office 12.0 Access Database Engine OLE DB Provider installed on your computer.
|It is important to have the data provider of the “bitness” same as TestComplete has (32- or 64-bit), otherwise, you will get the “The needed data source driver is not installed...” error message. So, if you use 64-bit TestComplete, you must have the 64-bit version of the provider.|
You can get this data provider as part of the following software:
Microsoft Access Database Engine 2010 Redistributable. You can download it on the Microsoft web site:
Again, make sure to download and install the 32- or 64-bit installation package that matches the TestComplete version you use.
If you have 32-bit Microsoft Office 2010, the installation of the 64-bit provider will fail. In this case, perform the following steps to install it:Show StepsHide Steps
Run the installer with the
Run the Registry Editor. To do this, open the Start menu, type regedit and press Enter.
Find the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths.
Delete or rename the mso.dll registry value. Otherwise, the data provider will get corrupted after the first Excel run.
