Question: How can I find out the version of Creator used to built the PSoC3/5 project last time.
Answer: Open the <project>.cyprj file as a text file, you will see the last version of the tool used to generate the configuration for the project in the following format:
<component_generation v="PSoC Creator 1.0 Production" />.
<project>.cyprj file is located under the <project>.cydsn folder.
For eg: For the project abc, abc.cyprj file will be located under folder abc.cydsn.
