A lot of users like me have had issues enabling (or as you can call it installing) InnoDB within MySQL. InnoDB support is available in MySQL as a lot of users on the forum pointed out, but not enabled by default. To enable it, please follow the instructions below.
&lt;<br /&gt;>1. Open the W:\usr\local\mysql\bin\my-small.cnf file in Notepad or any other text editor of your choice. &lt;<br /&gt;>2. Make sure the following lines appear as shown below - &lt;<br /&gt;>
&amp;#35; Uncomment the following if you are NOT using innodb tables &lt;<br /&gt;>&amp;#35;skip-innodb &lt;<br /&gt;>
&amp;#35; Uncomment the following if you are using Innobase tables &lt;<br /&gt;>innodb_data_file_path = ibdata1:100M &lt;<br /&gt;>innodb_data_home_dir = /usr/local/mysql/data/ &lt;<br /&gt;>innodb_log_group_home_dir = /usr/local/mysql/data/ &lt;<br /&gt;>innodb_log_arch_dir = /usr/local/mysql/data/ &lt;<br /&gt;>set-variable = innodb_mirrored_log_groups=1 &lt;<br /&gt;>set-variable = innodb_log_files_in_group=3 &lt;<br /&gt;>set-variable = innodb_log_file_size=5M &lt;<br /&gt;>set-variable = innodb_log_buffer_size=8M &lt;<br /&gt;>innodb_flush_log_at_trx_commit=1 &lt;<br /&gt;>innodb_log_archive=0 &lt;<br /&gt;>set-variable = innodb_buffer_pool_size=16M &lt;<br /&gt;>set-variable = innodb_additional_mem_pool_size=2M &lt;<br /&gt;>set-variable = innodb_file_io_threads=4 &lt;<br /&gt;>set-variable = innodb_lock_wait_timeout=50 &lt;<br /&gt;>
3. You can modify the values to suit your needs, but the default ones work great. &lt;<br /&gt;>4. Restart the server. &lt;<br /&gt;>5. Go to PHPMyAdmin and click on &quot;"Show MySQL Runtime Information&quot;". &lt;<br /&gt;>6. Click on InnoDB hyperlink which will take you to a lower part of the same page. Just under that information table, you will find a link for detailed &quot;"InnoDB Status&quot;". &lt;<br /&gt;>7. On the top, what you are most likely to see is &quot;"InnoDB is disabled for this server&quot;". If not, you are good to go. &lt;<br /&gt;>8. To resolve the issue in #7, shutdown the server once more. &lt;<br /&gt;>9. Go to W:\usr\local\mysql\data\ and delete (or at least temporarily move) the files beginning with &quot;"ib_logfile*&quot; " and &quot;"ibdata*&quot; " where * indicates a number. &lt;<br /&gt;>10. Restart the server, and follow steps 5-7 above. You should hopefully be able to now see &quot;"InnoDB is available on this MySQL server&quot;". &lt;<br /&gt;>
That's it. Enjoy.
