At first I thought this was an issue with having v1.7 installed on the same box but Ive since tried it with another machine and the utils tool just errors.</p>\r\n<p>Seems to be an issue with the build?? or am i missing a component on my machine.

    "Html": "<p>Hi Cheeso,</p>\r\n<p>On my own laptop which has not had the v1.7 stuff installed, Ive unpackaged the Utils zip &nbsp;and tried to run the&nbsp;DotNetZip-WinFormsTool.exe - the generic windows send error details window opens. This contains the following details:</p>\r\n<p>&nbsp;</p>\r\n<p>EventType : clr20r3 &nbsp; &nbsp; P1 : dotnetzip-winformstool.exe &nbsp; &nbsp; P2 : 0.0.0.0 &nbsp; &nbsp;&nbsp;</p>\r\n<p>P3 : 4a32a3a3 &nbsp; &nbsp; P4 : system.windows.forms &nbsp; &nbsp; P5 : 2.0.0.0 &nbsp; &nbsp; P6 : 4889dee7</p>\r\n<p>P7 : 2328 &nbsp; &nbsp; P8 : 5d &nbsp; &nbsp; P9 : system.argumentoutofrange &nbsp;</p>\r\n<p>This same behaviour happens on my dev &nbsp;machine as well. If I remove the v1.8 and install the v1.7 (either msi or zip build) the v1.7 forms tool opens correctly.</p>\r\n<p>I've built an sfx package I've built which has password encryption (aes 256) and contains multiple password pkzip encrypted zips. When excuting this exe via cmd i get the message &quot;Program to big to fit in memory&quot;. However the sfx file is only 725 bytes.</p>\r\n<p>I'm assuming these 2 issues are connected and nothing to do with the build of the test exe however below is the code im using to created the archive. Basically i run through a directory pulling out a list of .vox files. If a zip already exists of the same name then it gets added else I create a new zip and add the file. A Second pass is then done using the zip file names to create a sfx package. (file names contain datetime strings).&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<div style=\"color:Black;background-color:White\">\r\n<pre>\r\n        <span style=\"color:Blue\">private</span> <span style=\"color:Blue\">void</span> BuildZip(List&lt;<span style=\"color:Blue\">string</span>&gt; filepaths, <span style=\"color:Blue\">string</span> zipFullName, <span style=\"color:Blue\">string</span> passWord, <span style=\"color:Blue\">bool</span> encryptAES256, <span style=\"color:Blue\">bool</span> selfextractexe, List&lt;<span style=\"color:Blue\">string</span>&gt; ammendedFileNames)\r\n        {\r\n            <span style=\"color:Blue\">if</span> (!File.Exists(zipFullName))\r\n            {\r\n                <span style=\"color:Blue\">using</span> (ZipFile zip = <span style=\"color:Blue\">new</span> ZipFile(zipFullName))\r\n                {\r\n                    zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression;\r\n                    zip.Encryption = encryptAES256 ?
