Characteristics of the application:
- default cost type & group library;
- project cost type & group library;
- copying of substantiations from different estimations;
- copying of contract specifications from different estimations;
- export to and import from estimations and cost type libraries from and to excel;

Unzip the file. Place it anywhere you want. It stays there. Start Estimator_1.99.26.xx.exe. If you do not have the correct java version, it opens the browser. So you can download it. If you double click it, first appears a warning dialog box. After agreeing, the program starts. Immediately there will be created a folder, with all the database files. The file and the folder must always remain together.

Change log
Have a look at the changelog.

Make first a copy of the DB folder and the old exe file. Place the new exe file in the same folder as where the DB folder is. Double click the new exe file and check if everything is okay. Yes? Then your update succeeded.

Have a look at the tutorial.

The program was initially developed to be able to calculate with rsx files. At the time there were no free alternatives. To give the program a wider applicability it has also a proposal library. If one has a default proposal it is very easy to use it again and again. In that context also the small spreadsheet alias dim pad on the side was developed. Prices can be rapidly updated with excel imports. User input let to several modifications. It was fun to create something like this. It is mainly a hobby project.

Operating system
This application works on all Windows platforms. If you work on an unix, an unix like, a linux or mac system, you can find the jar next to the download link for the exe. Use terminal and the command: java -jar Estimator_1.99.26.xx.jar.

False positive virus alert
If your download gets deleted after download. You can first install java. After that, you download the jar file instead of the zip with exe. This generates a warning too, but you can ignore that. Next, double click the jar. More information about false positives in this article: Antivirus companies cause a big headache to small developers.
